@@RollingWrench gotcha. I have a Chinese made GY6. Are these delete units exclusive to the ruckus or can they be used in a Chinese scooter with an appropriate pump? If so I will buy one as soon as they become available might even buy 2 lol.
Yes these are all great new items I’m all for it! 👍🏼👍🏼 but for the ones who has the Mikuni fuel pump now they can blow on the gas tank to push the gas up to the carb to prime but who would want to keep doing that right so the easiest fix for this is installing a fuel transfer pump/manual pump on the fuel line between the pump and carb. You can buy the smallest one you can find so it’s easy to tuck away. Just another branch that people need to know if we’re about helping the community. More power to you guys Big Mike! 🍻
i had the same problem, fixed it with a primer bulb from a boat mounted under the seat been working perfect for a while. after it sets for a while just sit down give a squeeze or two then hit the starter and within a sec or two she's running. total cost..about 8 dollars.
Oh ya! That will work in place of this for sure as far as priming. It’s just big and bulky and ugly on a ruckus. But your still stuck with the unreliable pump.
I have a garden tractor with a pulse type fuel pump and adding the check valve as close to the tank as possible corrected my start issues. I also have a fuel shutoff at the carb that i close whenever I shut it off so the gas is pretty much trapped in the line.
If your carb bowl is full, then it'll start with no issue. Then the vacuum pump will have plenty of time to catch up. Another issue you're facing is the pump need to be pumping, not pulling. Mount it low, by the tank, and this is again a non issue. Also, try using a battery that isn't half dead.
Ya that will help a tiny bit. Or you can just make out with your gas tank. That will get the gas up to the carb every time like clock work. But it still doesn’t fix the over under fueling issues you get with these super unreliable pumps. At least this has been my experience. I hate them soooo much, I spent hours and hours creating this :-). But each your own. If like the vacuum pump run with it. Jest keep that battery charged up :-)

No, we appreciate you! All your videos are very interesting and educational and definitely deserving of thumbs up, million thanks! My question to you is can an electric fuel pump and pulser be used on a Chinese GY6 150cc scooter that operates on gravity feed? I have a concern with gravity feed bikes, since the gas tank sits higher than the carb. That works fine on flat ground. But, how about when going up a steep hill? Would the tank still be higher than the carb? What if the carb ends up being higher than the tank going up a steep hill? No gas, no power! Will the scooter starts rolling backwards?

@RollingWrench I'm researching mikuni fuel pumps for my engine however this looks nice. How much fuel can this pump per minute/hr? Do you think it could supply enough fuel for my 575cc engine at around 95hp?
Same problem with lawn tractors that use a very similar vacuum pump system so your fuel is going back to the gas tank in about two days time and you try to start it 2 days later you're cranking for quite a bit before it fires off again!
Great video! Alternatively you could put the electric pump prior to the vacuum pump as a booster and wire it to the ignition switch, So it would come on and pump fuel to the carb on starting and then the OEM vac pump would take over during normal operation,
Why buy that pulsar when you can just wire it to the ignition starter switch , it'll power it only when cranking over the engine and shut it off when you let off the start button , and you can either let the original vacuum pump take over or even better replace the og pump with an electric small constant flow pump and power that one to directly to the ignition switch
@@ARVintageCycles Almost exactly my though. There is no sense in having that pump sending gas constantly at the carburetor while the key switch is on, carburetor eventually will overflow. That's why those pumps are commanded by the ECU, in order to activate or deactivate it when needed. Maybe if the pump controller is triggered by the spark signal... but flow-rate must be precisely adjusted. Or maybe if you add a second layer of control in order to deactivate the pump when the float valve closes. Dunno, this solution needs a little more thinking.

Have one on hyosung Aquila gv250. Tank is above the carbs. I have done everything to this bike and I mean everything. Carbs and all. Still dies upon throttle but it starts and idles perfect. I have to spray the carbs to rev normal. I have a feeling it's this vac fuel pump. It's my first one I've ever seen.
You are a life saver to the problems I am having, only thing is I tried to order the whole unit and sadly enough it appears it can only be ordered in the US. I am just a border away in Canada and want one real bad, do I have to drive the 2076.8 miles just to get one? lol
These pulse pumps are actually very reliable and are widely used by experimental aircraft. It's not the pumps' fault that the fuel is low and needs to be pumped up to the carb. It's the pumps' job to keep the fuel flowing to the carb AFTER the engine starts, not get the fuel there to start with. To do that, use a primer bulb like outboard motors use. Also, the vacuum line should be as short as possible and made from stiff rubber hose, not long soft fuel line. If you use an electric pump, you must insure that the pump pressure doesn't exceed the rated pressure of the carburetor. Otherwise the pump will overdrive the carb float valve.
When the pump is not activated, does it block the flow of fuel? What I’m wondering is if I can use this on a gravity, fed fuel tank. Those vacuum operated pet cocks have always been very unreliable for me. I would love to just put a manual petcock on, and then essentially use this pump to stop the flow. If you open the bike is off, and then let it flow when the bike is on.
What up brother! How you been? You still rockin that Perrywinkle ruckus? 👌such a dope bike! To answer your question, unfortunately no. Fuel will still gravity flow with the pump off. I know what you mean, the diaphragm in those vacuum fuel valves are not very reliable. I think it is best just to install a free flowing fitting onto the gas tank and inline, install a 3/16 manual shut off fuel valve.
I put a manual petcock on mine. The switch on the petcock stops the fuel flow. My vacuum petcock was stuck open (better than stuck closed I guess). The manual petcock works just fine.
Vacuum pumps come on many small engines, not just GY6's. I have them on a riding mower and a Polaris 500 quad. The only time I ever had problems is when trying to replace old fuel lines and the nipple's break off the pump. Cheapo plastic, what do those aluminum pumps come from, gonna look for those next time I need new fuel lines because I KNOW the nipp's will break off my plastic pumps.
I had this problems with vacuum pumps to supply fuel on my 2 twins carbys,,i fixed with a simple eletric pump whit a relay switch to the ignition 12 voltage ,,run when engine on an stops when you turn off the engine ,,easy,,
I have an 86 ski doo citation 250cc 1 cylinder. Pull start, many pulls before starts. No battery, only ac on lights. Can i install this with an ac,dc bridge rectifier?
Whilst I think this is great upgrade it should be noted most of the problems associated with el cheapo vacuum pumps are because of the use of ethanol fuel. Whilst most, not all, GY6 style engines can tolerate E10 fuel it turns the diaphragm in the fuel pump into a wibbly wobbly jelly like curtain instead of a semi rigid membrane that can 'pop' back and forth and so pump properly. Mikuni and Keihin vacuum fuel pumps currently made in Japan have ethanol tolerant diaphragms however, because ethanol also jellifies the non-metallic components of the typical CV carburetor (float needle tip, main diaphragm, air cut valve diaphragm, bi-starter seat) they don't work properly either. I use E10 with no problems in my cars and my motorcycles which are fuel injected but not in my scooters.
Great detain in the Video! I have a Vanguard 23hp vtwin motor I use on a surface drive md boat. If you're familiar with that setup do think your pump and pulsar unit would work, since you have adjustment on the pulse unit?
Hey, Rolling Wrench I have a 2003 Honda ruckus and someone cut the Fuel Pump Plug off and just left the brass connector without the plastic cover over it. Do you have a feul Pump Plug or what should I do? Thanks, man, you've been a great help.
Hi, first of all ... Cudos for developing your on electric pump controller... My question is: wouldn't you be able to control and avoid over heat with a cheap pwm module for a DC motor?
Bought one. Found out 2 wires on Maddog will turn off power when disconnected. The green and green/yellow stripe. I may have hooked up backwards. When turn on power running light came on but pulse motor did not? Did I fry it? Have purchased service time. Looking forward to figuring it out.
Dude, I know this comment has a long time but hope this help you: the green/yellow wire is positive for stop light. You must seek for the solid brown wire that is positive for tail light. Any solid green is ok for ground.
Those fuel pumps are common on two stroke snowmobiles. The diaphragms in them harden over time, especially when exposed to ethanol in fuel. The check valves that should prevent fuel returning to the tank are part of the diaphragms and are sensitive to age and contamination. You can generally get a rebuild kit for a few bucks with the diaphragms and seals to rebuild the pump which should get it working like new. The fact it couldn't pump fuel more than an inch or two above the tank level shows that pump isn't working properly anymore.
Those (vacuum) pulse fuel pumps are generally ran to the *crankcase* on riding mowers, not the intake. Constant vacuum does not power them. It needs to be cycled from pressure to vacuum to pressure to vacuum. Vacuum pulls fuel into the pump, pressure pushes it to the carburetor, and the cycle continues.
@@RollingWrench The crankcase pulses from vacuum to pressure, the intake at low load pulses from strong vacuum to weak vacuum, and under heavy load the intake pulses from low vacuum to low pressure. The crankcase is a more consistent source of power for a pulse fuel pump, which would explain why scooters have such a problem with them while millions of tractors run just fine with pulse pumps
How about running a high-flow fuel pump directly into the carb with a low pressure (1-2 psi) check valve in reverse acting as a relief valve dumping back to tank and just let her pump to it´s hearts content.
@@78dwk If you want to play around with these things you have to be careful not to set up a circuit that ends up filling a cylinder full of fuel and locking it up. It needs to be done with a lot of care. Thinking about it now I would go with a gravity fed system that is fed by the pump instead of a pump feeding the carb directly. This way if the pressure increases for some reason (dirt, etc..) you don´t inadvertently fill a cylinder up. I would have a pump fill a small volume tank (a soda can´s worth or less) that is found over the carb float so that the only pressure the carb would see is gravity fed which would be controlled by it´s height over the carb. You should be able to find a spot to put a soda can´s volume somewhere on the bike. You can place a return line at a high point in this secondary tank so that when the pump fills it to that point it simply spills further flow back to the main tank. The fuel pump would need a standard low pressure check valve to feed the secondary tank so that when the system/bike is off the secondary does not bleed down. This ensures that the next time you go and start the bike up the secondary tank will be ready to rock. Ideally you would wire in a level sensor that would turn the pump on and off after reaching a certain level in the secondary tank so that the fuel pump is not always going when it does not need to. You would not need a processor/controller for it as it can all be wired from the devices itself. Good luck.
Hey mate, ive gotten a cheap Chinese quad and had the issue after running out of fuel. Ive been on the safe side and replaced the vacuum pump, fuel lines and petcock then the coil was shot so got thst and new spark plug. Now have spark but its like its still starving for fuel and wont start. You mentioned the fuel tank being above, ours is above but still has the vacuum operated pump, i was going to remove all together but dont want to flood the carb. Any ideas
$233 ordered with pump and pulsar, no shipping. Got an old UTV project I'm tired of dealing with. New carb, filters, fuel lines, sparkplug and everything and she's still running like garbage. New ignition coil and this pump will save it. If not I'll light it on fire lol I'll try to remember to come back and let ya'll know how it comes out

@@RollingWrench That's really awesome and I salute you for it! As a patent holder myself, I can't begin to extole the Importance of securing your product. I know the amount of work put into a project, the expense, and the time it takes to secure a patent. You have every right to be proud of this.

I think this would be a huge market potential for your product.
Learning altot about gy6 engines from you. Was wondering if this will work with a tao tao racer 50. I believe it has a vacuum pump not quite sure, but having same issues. Have recently done an cc upgrade using pro build, from 49 cc to 80cc.
The petcock on the taotao is gravity fed. The tank is placed higher which forces the fuel to go down. The vacuum attachment only opens and closes the petcock-that’s all it does. If it actually acted as a pump, fuel would be sucked into the vacuum hose. I have 2 of the same bikes (taotao pony 50s). I also did the 80cc upgrade-huge difference! Question-are your valves chatty with the 80? I adjusted my valves several times and still. I know it’s the valves because I did a test-I adjusted the valves to zero (tappet touching the valve head) and the sound went away. Anyway, the petcock on mine was stuck open (better than stuck closed I guess). I changed it to a manual petcock. Works just fine.
What would have if I didn’t get that module and just had it wired in to ignition switch and just gave it the 2 psi the whole time. Running and idling , would it be ok. It would be just like a car
Hi I have a Toro dingo Mini skid steer tx 427 you can search it up to get an idea , anyways it has exactly one of those fuel vacuum pump that you mentioned in the video . Now I changed the fuel filter I can see gas inside the filter but when I try turning it on only The fan starts working , It won’t Crank at all , the gas tank sit all the way at the bottom . Will that Honda Product work for The walk behind toro dingo tx 427?
It's not the fact that it's vacuum operated that is the problem. Marine outboard engines have used them for decades and they operate for years without issues, many of which are pull start. It's probably poor quality or engineering in these particular parts or low/poor vacuum pressure from the engine.
The pressure from the pump fills up the float bowl. Once full, the flow is stopped inside the carburetor by the needle and seat. If it needs more, there is more on tap with the pressure behind it. We have done a ton of testing. All good, nothing to worry about on your end.
If you’re doing a go kart budget build and you’re broke and this solution is way to expensive typically pulse pumps are the solution but if they start jamming open it up and clean it or just buy a new one they’re cheap. i take good care of my motors and don’t spend tons of money on something like this
so does it always pump fuel when the bike is running, and you calibrate it to keep the bowl filled, but not over filled? it's a trial and error at first, i assume, right?
i have a Kymco Granding 250cc scooter, its not been running since July or August last year, and i just start to run it again yesyerday and today... and the issue i have now is when i go uphill it feel like it going to stall or dosent have enough power or gas running, what could the problem be? is it a power pump issue or what? it use the round shape power pump like onr u show in this video
@@RollingWrench i am down but also in korea for another year....large ruckus/zoomer crowd here in military...just tell me what i need to do to be part of it
It's not a vacuum driven pump. it's supposed to be driven by the backpulse of the pistons. They're very reliable. I don't see where that port goes on your manifold, but I would guess straight into the block and not the fuel runner. When this part seems to fail don't immediately shoot the messenger. Chances are there is another problem up the chain. It's like when the autozone guy plugging into your obd2 and seeing the hego sensor failures and tries to sell you all of them when there's clearly a problem further up. All the sensors can't go out at once. It's more often than not a fuel pump or pressure reg or etc. In your case and the most common problem is valve cover gasket, crank seal, pcv or other failure that is causing that fuel pump to not get the full back pulse. That back pulse is going to take the path of least resistance. I have that same pump on 115hp johnson outboard and I've running it for the last 41 years. Those pumps used to come stock on the old columbia parcar/harley davidson P4 cruiser golf cars. Hence how I got it some 41 years ago. Just didn't think golf cars was going to be a life long carrier. Only mod i had to do was tap the hole and put a nipple to hook the pump up. Now that being said I do like your solution, and if that pump ever fails I will be using that mod, damn skippy. That would fit inside the same space. I dig it.
It’s the only way to go. The biggest issue is cranking these big motors over and killing the battery before the fuel reaches the carb. Ya you can give the tank a blow (lol)
I run that old cheap pump on a Lincoln electric ranger 8 generator welder, there are no taillights to hook up to so would this new device be wired straight to the battery?
figure a way to power this pump on my inverter generator. I got the same damn pulse fuel pump that takes forever to pump fuel up to the carb...this causes me to use the mouth trick each time and pressurize the tank to get fuel to carb.
Got problem with Kiwasaki 23hp engine, I have replaced 3 FP's without success; ie, low volume after a few minutes. Will this pump delete kit supply enough fuel for the 726cc engine?

When the pump is not activated, does it block the flow of fuel? What I’m wondering is if I can use this on a gravity, fed fuel tank. Those vacuum operated pet cocks have always been very unreliable for me. I would love to just put a manual petcock on, and then essentially use this pump to stop the flow. If you open the bike is off, and then let it flow when the bike is on.
What up brother! How you been? You still rockin that Perrywinkle ruckus? 👌such a dope bike! To answer your question, unfortunately no. Fuel will still gravity flow with the pump off. I know what you mean, the diaphragm in those vacuum fuel valves are not very reliable. I think it is best just to install a free flowing fitting onto the gas tank and inline, install a 3/16 manual shut off fuel valve.
I put a manual petcock on mine. The switch on the petcock stops the fuel flow. My vacuum petcock was stuck open (better than stuck closed I guess). The manual petcock works just fine.
Thx for ur hard work.. can’t wait for ur turbo set to hit the market… I told me wife I’m saving for a new car.. 😅
Vacuum pumps come on many small engines, not just GY6's. I have them on a riding mower and a Polaris 500 quad. The only time I ever had problems is when trying to replace old fuel lines and the nipple's break off the pump. Cheapo plastic, what do those aluminum pumps come from, gonna look for those next time I need new fuel lines because I KNOW the nipp's will break off my plastic pumps.
ACDC sounds like lucus the prince of darkness. God bless
I had this problems with vacuum pumps to supply fuel on my 2 twins carbys,,i fixed with a simple eletric pump whit a relay switch to the ignition 12 voltage ,,run when engine on an stops when you turn off the engine ,,easy,,
I have an 86 ski doo citation 250cc 1 cylinder. Pull start, many pulls before starts. No battery, only ac on lights. Can i install this with an ac,dc bridge rectifier?
should work fine if you install this with an ac,dc bridge rectifier, Godbless
I like the idea. How would I hook this up for a commercial walk behind mower and how much does this system cost??
Whilst I think this is great upgrade it should be noted most of the problems associated with el cheapo vacuum pumps are because of the use of ethanol fuel. Whilst most, not all, GY6 style engines can tolerate E10 fuel it turns the diaphragm in the fuel pump into a wibbly wobbly jelly like curtain instead of a semi rigid membrane that can 'pop' back and forth and so pump properly. Mikuni and Keihin vacuum fuel pumps currently made in Japan have ethanol tolerant diaphragms however, because ethanol also jellifies the non-metallic components of the typical CV carburetor (float needle tip, main diaphragm, air cut valve diaphragm, bi-starter seat) they don't work properly either. I use E10 with no problems in my cars and my motorcycles which are fuel injected but not in my scooters.
I appreciate you , I have a question that can I use a electric fuel pump without pulser
Great detain in the Video! I have a Vanguard 23hp vtwin motor I use on a surface drive md boat. If you're familiar with that setup do think your pump and pulsar unit would work, since you have adjustment on the pulse unit?
I have plenty of people using these on boat engines
Hey, Rolling Wrench I have a 2003 Honda ruckus and someone cut the Fuel Pump Plug off and just left the brass connector without the plastic cover over it. Do you have a feul Pump Plug or what should I do? Thanks, man, you've been a great help.
Hi, first of all ... Cudos for developing your on electric pump controller... My question is: wouldn't you be able to control and avoid over heat with a cheap pwm module for a DC motor?
Thank you. Maybe? Try it
That Ruckus is sick.
Very nice and useful video!
Thanks for sharing!!!
Greetings from Mayorca Spain
Good solutions for motorcycle that use a vacum pump..vacum pump kind like sucks...this is really a good inovation for old bike.
Bought one. Found out 2 wires on Maddog will turn off power when disconnected. The green and green/yellow stripe. I may have hooked up backwards. When turn on power running light came on but pulse motor did not? Did I fry it? Have purchased service time. Looking forward to figuring it out.
Dude, I know this comment has a long time but hope this help you: the green/yellow wire is positive for stop light. You must seek for the solid brown wire that is positive for tail light. Any solid green is ok for ground.
Those fuel pumps are common on two stroke snowmobiles.
The diaphragms in them harden over time, especially when exposed to ethanol in fuel. The check valves that should prevent fuel returning to the tank are part of the diaphragms and are sensitive to age and contamination.
You can generally get a rebuild kit for a few bucks with the diaphragms and seals to rebuild the pump which should get it working like new. The fact it couldn't pump fuel more than an inch or two above the tank level shows that pump isn't working properly anymore.
True. And there is better ways than those dang things!
Thks four your excellent video I have a Peugeot v clic is start today spilling gasoline through the tank breather whitch reason thank you so much
I have bad experience in Yamaha. Majesty electric fuel pump,
Those (vacuum) pulse fuel pumps are generally ran to the *crankcase* on riding mowers, not the intake. Constant vacuum does not power them.
It needs to be cycled from pressure to vacuum to pressure to vacuum.
Vacuum pulls fuel into the pump, pressure pushes it to the carburetor, and the cycle continues.
Yes that is true on a tractor. Unfortunately not on a scooter. However the intake pulses as well. In case you didn’t know.
@@RollingWrench The crankcase pulses from vacuum to pressure, the intake at low load pulses from strong vacuum to weak vacuum, and under heavy load the intake pulses from low vacuum to low pressure.
The crankcase is a more consistent source of power for a pulse fuel pump, which would explain why scooters have such a problem with them while millions of tractors run just fine with pulse pumps
@@Texassince1836 what I’m trying to say is the scooters don’t have that option. The only breather hose is on the head. It can’t be restricted.
Can the vacuum help if you have a problem with the gravity fed carbs?
How about running a high-flow fuel pump directly into the carb with a low pressure (1-2 psi) check valve in reverse acting as a relief valve dumping back to tank and just let her pump to it´s hearts content.
You can do that too
@rafaellastracom6411 can you give me more info in this idea parts and hook up info ,Thanks Godbless
@@78dwk If you want to play around with these things you have to be careful not to set up a circuit that ends up filling a cylinder full of fuel and locking it up. It needs to be done with a lot of care. Thinking about it now I would go with a gravity fed system that is fed by the pump instead of a pump feeding the carb directly. This way if the pressure increases for some reason (dirt, etc..) you don´t inadvertently fill a cylinder up. I would have a pump fill a small volume tank (a soda can´s worth or less) that is found over the carb float so that the only pressure the carb would see is gravity fed which would be controlled by it´s height over the carb. You should be able to find a spot to put a soda can´s volume somewhere on the bike. You can place a return line at a high point in this secondary tank so that when the pump fills it to that point it simply spills further flow back to the main tank. The fuel pump would need a standard low pressure check valve to feed the secondary tank so that when the system/bike is off the secondary does not bleed down. This ensures that the next time you go and start the bike up the secondary tank will be ready to rock. Ideally you would wire in a level sensor that would turn the pump on and off after reaching a certain level in the secondary tank so that the fuel pump is not always going when it does not need to. You would not need a processor/controller for it as it can all be wired from the devices itself. Good luck.
@@rafaellastracom6411 thanks for the info Godbless
Hey mate, ive gotten a cheap Chinese quad and had the issue after running out of fuel. Ive been on the safe side and replaced the vacuum pump, fuel lines and petcock then the coil was shot so got thst and new spark plug. Now have spark but its like its still starving for fuel and wont start. You mentioned the fuel tank being above, ours is above but still has the vacuum operated pump, i was going to remove all together but dont want to flood the carb. Any ideas
Just ordered mine! I’ll make a video about it as well! 🙏🏽
My Riding Lawn Mower has the Vacuum pump. The Tank is well above the engine and carburetor. Do you believe that the pump is actually necessary?
My Simplicity Champion zero-turn has the round black one. Mine was working fine until the vibration cracked the plastic off
Can I install this in my gilera DNA 180 hope you can help, how much does it cost thanks alex
Awesomeness! Just ordered mine! Where do you recommend I mount the pulsar unit? Also will I ever need to play with the screw on it?
Sweeet! Thanks dude. Mount the pump in the stock ruckus location and the pulser anywhere away from heat.
$233 ordered with pump and pulsar, no shipping.
Got an old UTV project I'm tired of dealing with.
New carb, filters, fuel lines, sparkplug and everything and she's still running like garbage.
New ignition coil and this pump will save it. If not I'll light it on fire lol
I'll try to remember to come back and let ya'll know how it comes out
You forgot...
It was a clogged vent line from a dirt wasp. Had nothing to do with fuel so I didn't end up using it
I JUST ORDERED ONE! WHAT DO YOU RECOMMEND TO CAP OFF THE VACUUM NIPPLE ON CARB
Nice! Thanks dude. Just use a rubber nipple. They can be purchased at an auto parts store

I been checking some of your contents and I love them all. I just have one question. 1p61QMK engine those that means only a 61 mm bore kit works? Or how high can I go. 170cc 61QMK ENGINE I want to make it faster and I’m also looking to purchase the reveno clutch kit
How long does it take connect to deliver
I take it that you desinged this unit & if you did, did you secure it with a patent?
Oh yaaa
@@RollingWrench That's really awesome and I salute you for it! As a patent holder myself, I can't begin to extole the Importance of securing your product. I know the amount of work put into a project, the expense, and the time it takes to secure a patent. You have every right to be proud of this. Btw, I think you should do a video on installing it on a mower, esp a riding mower. Not everyone has a bike or a mule, but almost everyone in the US has a mower, even if they only rent. I think this would be a huge market potential for your product.
Learning altot about gy6 engines from you. Was wondering if this will work with a tao tao racer 50. I believe it has a vacuum pump not quite sure, but having same issues. Have recently done an cc upgrade using pro build, from 49 cc to 80cc.
The petcock on the taotao is gravity fed. The tank is placed higher which forces the fuel to go down. The vacuum attachment only opens and closes the petcock-that’s all it does. If it actually acted as a pump, fuel would be sucked into the vacuum hose. I have 2 of the same bikes (taotao pony 50s). I also did the 80cc upgrade-huge difference! Question-are your valves chatty with the 80? I adjusted my valves several times and still. I know it’s the valves because I did a test-I adjusted the valves to zero (tappet touching the valve head) and the sound went away. Anyway, the petcock on mine was stuck open (better than stuck closed I guess). I changed it to a manual petcock. Works just fine.
What would have if I didn’t get that module and just had it wired in to ignition switch and just gave it the 2 psi the whole time. Running and idling , would it be ok. It would be just like a car
Hi I have a Toro dingo Mini skid steer tx 427 you can search it up to get an idea , anyways it has exactly one of those fuel vacuum pump that you mentioned in the video . Now I changed the fuel filter I can see gas inside the filter but when I try turning it on only The fan starts working , It won’t Crank at all , the gas tank sit all the way at the bottom . Will that Honda Product work for The walk behind toro dingo tx 427?
Could you upgrade a gy6 engine to the max? Then proceed to put it on your custom stretched Honda Navi?
I never had a problem with the old style pumps in 30 years maybe because I keep my full system clean an take care of stuff
If it’s not broke don’t fix it they say
Come funzionano le pompe che hai detto che non vanno bene? Nel senso, si collega solo entrata benzina e uscita che va al carburatore?
@Rolling Wrench you mentioned selling gy6 171 already to go. How much is that?
It's not the fact that it's vacuum operated that is the problem. Marine outboard engines have used them for decades and they operate for years without issues, many of which are pull start. It's probably poor quality or engineering in these particular parts or low/poor vacuum pressure from the engine.
I have a 2009 Yamaha Rhino 450. Will this work with it? Thanks in advance Dan
I just watched the video how's the pulser unit know if it's over fueling are under fueling the engine is going to use more when under a loud
The pressure from the pump fills up the float bowl. Once full, the flow is stopped inside the carburetor by the needle and seat. If it needs more, there is more on tap with the pressure behind it. We have done a ton of testing. All good, nothing to worry about on your end.
Can o use this part in a Honda pressure washer GX 390?
Please let me know. Thanks
If you’re doing a go kart budget build and you’re broke and this solution is way to expensive typically pulse pumps are the solution but if they start jamming open it up and clean it or just buy a new one they’re cheap. i take good care of my motors and don’t spend tons of money on something like this
Also applies to some Chinese generators, and it's even more of a pain as you have to pull start the damn things 😅
So I have a gy6 50cc ice bear mad dog with vacuum problems so the pump doesn’t work well if I get this will I not need vacuum anymore
So I have a 1986 spree Honda and it needs a crankshaft we're wold I be able to get one?
L’uscita del carburante varia in base ai giri del motore?
New subscriber from philippines can vlog a full video how to build a simple and budget meal gy6.. THANK YOU😊😊😊
so does it always pump fuel when the bike is running, and you calibrate it to keep the bowl filled, but not over filled? it's a trial and error at first, i assume, right?
As long as the key is on it will pump fuel. The float in your carburetor will stop the fuel when it gets full
Ce una diversificazione quando il motore è ad bassi regimi o alti regimi?
How much pressure does it put out?
Could you put on a the regular electric fuel pump that's for an automobile but with low pressure?
The Honda pump is 2psi
Run the hose to the carburetor. The carburetor has a float it is an on and off switch for the gas.
Shows it out of stock ? When would it be available?
2-3 weeks
Do you work on Atv motors or better question do you rebuild customer engines.
👍🏼🙌🏻🙌🏻glad they worked out for you Matt!
Check yaaa! 🙌
Wait my gas tank is above the carb but is a vacuum bc I sucked on the vacuum line and it pushed fuel out.
i have a Kymco Granding 250cc scooter, its not been running since July or August last year, and i just start to run it again yesyerday and today... and the issue i have now is when i go uphill it feel like it going to stall or dosent have enough power or gas running, what could the problem be? is it a power pump issue or what? it use the round shape power pump like onr u show in this video

Good Job my dude!! Good Job!
It's not a vacuum driven pump. it's supposed to be driven by the backpulse of the pistons. They're very reliable. I don't see where that port goes on your manifold, but I would guess straight into the block and not the fuel runner. When this part seems to fail don't immediately shoot the messenger. Chances are there is another problem up the chain. It's like when the autozone guy plugging into your obd2 and seeing the hego sensor failures and tries to sell you all of them when there's clearly a problem further up. All the sensors can't go out at once. It's more often than not a fuel pump or pressure reg or etc. In your case and the most common problem is valve cover gasket, crank seal, pcv or other failure that is causing that fuel pump to not get the full back pulse. That back pulse is going to take the path of least resistance. I have that same pump on 115hp johnson outboard and I've running it for the last 41 years. Those pumps used to come stock on the old columbia parcar/harley davidson P4 cruiser golf cars. Hence how I got it some 41 years ago. Just didn't think golf cars was going to be a life long carrier. Only mod i had to do was tap the hole and put a nipple to hook the pump up. Now that being said I do like your solution, and if that pump ever fails I will be using that mod, damn skippy. That would fit inside the same space. I dig it.
It’s the only way to go. The biggest issue is cranking these big motors over and killing the battery before the fuel reaches the carb. Ya you can give the tank a blow (lol)
I've done everything you mentioned 😂
I appreciate your support so much dude 🙏🏻💯
will this work for an arctic cat 400 with a vacuum pump?
Would this fuel pump work for a methanol build?
Maybe… haven’t tried.
Do you think that would work with a 2005 V Twin 750 Kawasaki ATV
I run that old cheap pump on a Lincoln electric ranger 8 generator welder, there are no taillights to hook up to so would this new device be wired straight to the battery?
12v that can be turned on and off.
figure a way to power this pump on my inverter generator. I got the same damn pulse fuel pump that takes forever to pump fuel up to the carb...this causes me to use the mouth trick each time and pressurize the tank to get fuel to carb.
Never had a problem with one that hasn’t failed mechanically.
86 Craftsman Garden tractor with a vacuum pulse pump with gas tank above carb.
i wonder if this could be adapted to an outboard motor that uses a small vacuum pump ? 94 mercury 75 hp 3 cylinder.
Got problem with Kiwasaki 23hp engine, I have replaced 3 FP's without success; ie, low volume after a few minutes. Will this pump delete kit supply enough fuel for the 726cc engine?
If it had a single carburetor it shouldn’t be a problem
These pumps are pulse pumps not a vacuum pump it’s pressure in fuel out
Last time I checked the intake doesn’t produce pressure…
This sounds like it would work on my brute force 750
I’m interested in the fuel pump also but I didn’t see in the link
