Great explanation nothing missed out no assumptions at all. Thankyou
THE BEST EXPLANATION EVER
THANK YOU SO MUCH MASTER
This is excellent; comprehensive yet concise. I learned a lot - thank you.
thank you for the educational video. Just what the type of info I was searching for
Great information. I'm converting over to a Sniper system and this is perfect for what to do to upgrade my fuel system.
Thanks for the video!
EXCELLENT PRESENTATION
My car's fuel pump malfunctioning and I gonna change it and come across your video. It make me easy to buy more suitable one. Thank you
What I was looking for... good video
very comprehensive great job.
Impressive video.
I changed the fuel pump in truck and no vapour lock.
Great vid thanks for posting
Excellent, thank you.
Thanks for the video. It was pretty good info. 👍👍👍
Nice video. I have a Sniper EFI installed in my 73 Chrysler Imperial ad it's working great, however the fuel pump is a bit noisy considering a luxury sedan environment. I'd like to know if there's a quieter electric in line fuel pump for my application. Thanks.
Thank you for sharing :)
Wow, thanks. I learned
Glad it helped
Thanks
Thank you so much sir
I have a '72 International Loadstar grain truck with a 345 V8 being fed by a Carter Thermoquad 4 bbl carb. What fuel pump would you recommend?
Lol I'm here trying to get a aftermarket fuel pump for my 1969 MG Midget Project car.
FUCK $150 for an OEM fuel pump, All I gotta do is get fuel from here to there. And it's an electronic fuel pump.
Thank you
What in-tank electric fuel pump can I use on a 2008 Subaru Impreza and should I upgrade from my stock oem fuel injectors??? Especially, since my current modifications such as: 3" single exhaust pipe catback (my stock vehicle exhaust system was a dual exhaust set up), Cold Air Intake with a throttle body spacer, and $58.00 Chip connected inside the engine compartment (which I'm not even sure makes a difference, don't judge me). Any suggestions or anything??? Help!!!!
I have a 300 inline in my 72 F250 is plan to use a sniper EFI, Ill be using an auxiliary tank as my primary and I'm curious as to what pump you would recommend? I realize most of these comments are from 2 years ago but it can't hurt to ask
My car came with a 160 gph pump so your saying that was good for 1700 hp ? It was a dead head to if I went with a 120 would it run cooler maybe? Or does that matter
help me to know which pump is good for my Toyota cienta with engine power 1490
I have a 383 sbc full roller engine. Any ballpark idea of which pump it would need?
Hi, are all inline electric fuel pumps also pull-through fuel pumps? My truck can sit for weeks and sometimes months between starts. I want to use an electric fuel pump to prime the carburetor in my truck before I start it. After the truck starts then I turn the electric fuel pump off and have the engine just run on the stock mechanical pump. But the mechanical pump has to be able to pull fuel through the turned-off electric fuel pump. That's why I ask if all electric fuel pumps are pull-through pumps.
Also are there temperature limitations on an electric fuel pump? For example will an electric pull-through fuel pump work ok at -10*F that has been sitting in -10*F temperatures for several weeks?
Hey I have a Holley blue electric fuel pump that's making a lot of noise when it's on is that normal? Is there any way to silence ? Or should I just buy another fuel pump from you guys thats more quiet
where the site link to determine the pump size and psi ect for a fueling system as mentioned??
Which one I can buy for my auxiliary diesel tank
I have a 91 plymouth sundance 2.2 throttle body it has 90 horse an 110 torqe cant find no info on it need a new tank and pump what pump would i need
Why is it that some vane style pumps that flow for EG: 220 gph are rated to 650 odd HP and with an EFI pump only require 54gph with same sized fuel lines. Considering going the the Black EFI Screw type design , just trying to understand the difference. Hi from Australia :)
Looking for a inline pump to feed a turbo blow thru 5.3 setup 900hp max
What about casual driving fuel pump for a 305 gen 1
I just installed a 2002 5.7 Vortec Kodiak Marine engine in my 1981 Chevy 3/4 ton truck. I equipped the engine with my stock Quadra-jet 4-brr carburetor and had to use an electric fuel pump , due to the Kodiak 5.7 engine not having the hole for the mechanical pump.
I contacted the engine manufacturer and was told that the engine has a 383 stroker camshaft and the engine produces about 300hp.
I am having a problem with the engine wanting to die out (it does) due to lack of enough fuel at intermittent times and will not start until a minute or two passes.
Since i put the engine in last week i am currently on my third fuel pump. The first two were duds the same day. Today i went to the local auto parts store and purchased a Mr. Gasket brand pump that is rated at 4 to 7 psi. I have the pump in the engine bay with the hood completely off. After getting on the throttle a few times it stalled out on me and would not start until about a minute or two passed.
My question to you please :
(1) What size fuel line hose should i use ?
(2) What pump do you recommend for my setup ?
(3) And what do i do about the vapor return line that is left over now that i am no longer using an mechanical pump ?
Please help. Thank you.
5/16" fuel line should be just fine for 300hp. If you are using pump gas you will need a fuel pump capable of flowing at least 120lph or 32gph at 7psi. I believe your installation of the pump in the engine bay is your biggest problem! An electric fuel pump is much better at pushing fuel than pulling fuel so it needs to be as close as possible to the fuel tank and mounted below the lowest fuel level so it is gravity fed. If you are using the 12S Mr Gasket pump you should be fine as long as you mount it correctly and in the proper location! Thx J
@@HolleyPerformance Thank you so much ; i already moved the fuel pump and used the 5/16" fuel line and it works fine now. Thanks again , i really appreciate your help.
@@manfredschield9745 Glad we could help!
For carbed applications, I have always used the tried and true Carter electric pumps, and then a Holley regulator. I have only ever bought one Holley pump, and it had to be replaced within a week. It started leaking between the motor and the pump head, supposedly a sealed assembly. The Holley 12-803 type regulators have worked very well for me. The pumps not so much. That leak chased me off forever, and I will never trust or buy one again.

Got any high pressure high GPH diesel pumps that cost less than $200.00 ??? I have a 5.9L 12 valve P-pump Cummins and I am looking for a reliable affordable pump with 3/8 or 1/2 inlets/outlets that can maintain a minimum of 20PSI at full throttle
really good video.
I have a question, what if I need a fuel pump ASAP for my stock engine, just to get it running, but plan on increasing horse power next year? should I buy a pump for the horsepower it has at the moment and upgrade later? or can a stock 125hp engine run with an oversized pump for 200hp and have no problems?
That's a bit of a tricky question. A lot of it depends on the type of pump used and how much of an increase in horsepower you plan to do in the future. Most pumps should be able to handle under-performing when used with a quality return style regulator and adequate return line. But remember that if you restrict a larger fuel pump you will create more heat and over time it can cause damage or even failure. There are plenty of budget minded pumps available today that would supply your stock engine. Why not use one of these now and save your money till you know exactly what you will need for the upgraded engine! thx J
i have a bypass12-887 i have a vacumm port outlet on it do that line have to be hook up
Great info, the formula at 2:30 didn't exactly specify whp? or crank hp? Which one to consider in the calculation?
Fuel calculations like this are always crank horsepower.
I have a 91 Camaro RS with a stock 305/5.0 TBI. What do you recommend for my car?
I want to do an LS-3 swap run on flex fuel .. I want to add nitrous in the future .. With my carbureted car I needed about 3 PSI for my Nitrous .. spray bar under the carb.. I have not yet figured out what pressure an LS nitrous spray bar uses..
I plan to upgrade my gas tank so I can run an in the tank fuel pump .. I like the Holley Sock type fuel filter but have notices many other brands use similar ..
When I added Nitrous to my 1979 Z-28 Camaro I added a simple in line electric pump .. I removed my mechanical fuel pump that used a return fuel lien and also had a charcoal Canister to store gasoline fumes.. With Engine vacuumed it sucked those gas fumes into the intake instead of loosing them to the atmosphere which would cause a little air pollution ..
Sadly I removed all of that and later discovered the High Volume pump that cam on my Camaro put out more fuel pressure than the small Holley Electric pump .. I also found a kink in the stock steel fuel line coming out of the gas tank .. I replaced that with rubber fuel line .. I also used an adjustable fuel pressure regulator .. The car still has a small steel fuel return line and I may still have the Charcoal Canister ..
I have read quite a lot on high pressure fuel systems yet have heard no mention of a Charcoal fuel canister ..
I like the idea of a PWM pump set up the best.. I like the Haltech ECM and wiring Harness.. I did not find a similar product by Holley so far..
I need to research if the Haltech 2500 series ECM can already do PWM or if I have to add a second ECM with fuel pressure sensors.. I also of course need a GM type Flex fuel ethanol content Sensor..
\ I does look like Holley offers some of the better Motor mount kits for LS swaps but they web page is terrible for info as is their page for a complete radiator set up ..
Our HP and Dominator ECU's can both handle pulse width modulation of your fuel pump. I will pass the info on to our web designers about the difficulties in navigating the website! Thx J
@@HolleyPerformance It's not difficult to Navigate It just simply does not include the necessary information to select the correct radiator ect .. for LS swaps .

How do I plum the return line in sbc 350 electric fuel pump
I have a Dodge 318(TBI stock), and plan on converting it to carb (with a regulator). And need to replace the stock in-tank fuel pump. I have considered just installing an inline pump ahead of the tank(90' Ram). Is that a bad idea?
Has the in-tank pump failed? if not you can get a bypass fuel pressure regulator to reduce the pressure down to work with a carburetor.
www.holley.com/products/fuel_systems/fuel_pumps_regulators_and_filters/regulators/
If your pump is bad then yes, you can replace it with an external pump. Keep the pump as close as possible to the tank and below the low fuel level. Some plumbing work will be necessary to make it all work but look at these pumps if you choose to go with an external unit. www.holley.com/products/fuel_systems/fuel_pumps_regulators_and_filters/fuel_pumps/carbureted_fuel_pumps/ Thx J
Not mentioned are the AN fittings. For example. If you run a 3/8" fuel tube (steel, aluminum, rubber or teflon), the I.D. is .375". Using AN 37 degree flare fittings, the I.D. of a -6 fitting is 0.285" which is 0.090" smaller than the tubing. Going to -8 tube fitting the I.D. is 0.390" which is 0.015" larger than the tubing. Most people that have not used AN fittings believe that a -6 is equivalent to 0.375 I.D. and that is not the case.
May I use electric fuel pump for pumping engine oil (hot oil) ?
what fuel pump for a Bentley turbo 1993 model, can someone please help me. and where I can buy one.
Can in tank gasoline pump replace in tank diesel fuel pump?
Ok I have a 1997 350 vortex converted over to carb in my 1987 Monte Carlo summit racing intake. I was wondering with electric fuel pump I’ll need ? The car stalls when I mash the gas. I’m currently running a cheap one. Don’t know the horse power, have Wilwood brakes, and running unleaded fuel. I need to purchase ASAP.
There are a lot of variables for fuel pumps!? Are you currently using a mechanical or electric fuel pump??

Wow.
I have a 1973 mustang with a pro-jection 2d Efi system
Would you recommend me a different fuel pump to use not the stocking one
I assume when you are referring to the "stock" fuel pump, you mean the electric unit provided in the Pro-Jection kit? The pump P#534-38 is a great pump and is matched to the Pro-Jection system very well. Unless you have added larger injectors or maybe forced induction the included pump will do just fine. We still offer replacement units under the part number I listed above if you need a new one. Thx J
great
I just need one to put in my auxiliary gas tank to dump that fuel into my main tank to fill up quickly
Excellent, thank you.
Note: Try holding your head still when talking.

ok so my 62 twin carb Corvair needs no more than 10 gallons per hour, thru dash 6 lines (after the T fitting stem which already is 11/32 ID rubber, this part OK for 91 octane if it's from Shell in Canada, not sure about other product, and its effect on the mechanical pump diaphragm.
these pumps had several poor quality re-issue and I may have wound up with one - did not go to internet sources
Not sure I understand your question?
I have a doubt, for some weber carburetors which electric pump do you recommend?
You didn't specify which Weber carb you have, in my experience with the side draft carbs they like to have about 3.5psi max. Assuming your wanting a self regulating fuel pump here are a couple of choices. the Holley 12-426 and 12-425

Most all of our other electric pumps would require and external regulator to bring the pressure down enough for the Weber. We have a large selection of regulators that would work, you can check them out here.

I have a MC 2150 on my 82 F150 302ci 4x4 with a c6 Auto trans. I bought the truck from a PO. If it has a carb on it but it has an electric fuel pump ( it's hardwired on a switch mechanical pump is still on block just not connected) would the Electic Fuel Pump be supplying too much pressure to the Accel Pump Diaphragm that Is used for a mechanical pump?
That all depends on what the specs are on the electric pump. It will push fuel past the needle and seat first (usually happens around 8+ psi of pressure), if you are getting a fuel leak at the accelerator pump it is probably a bad diaphragm. Thx J
HolleyPerformance Thank You, omw to Oriellys on Saturday and she died on me.. Accel was still leaking, tried priming her and the peddle snapped. TIG'ed the pedal, then tried priming and no gas. So my fuel pump was Fawked as well. changed pumps and diafram. she's get 14 to the carb. runs like a top. thanks man!
I need 10 psi or so lift pump with wire harness conect3d un to my battery Its 1995 3500K 6.5
Most of our pumps are only rated for use with gasoline and have not been thoroughly tested for use in diesel fuel. Your best bet is an aftermarket pump designed as a lift pump for diesel use. However, we do offer a few pumps that are diesel compatible, here is a link to those we offer! thx J

hi! I have a jeep cj7 with engine stroker 4.7 and carburetor edelbrock 600. what pump should I buy? preferably not noisy
The first thing you should do is get rid of that brand "E" carb!! LOL! All kidding aside, our Holley red or blue pump would work great for your set-up assuming that you are looking for an external "in-line" pump and not an in-tank unit. Heres a link for you. Remember to mount the pump as close to the tank as possible and lower than the lowest possible fuel level for best performance and life-span. Thx J

I have a Holley electric fuel pump part # 12-125. 125 GPH this pump works for ls swap ? ( engine vortec 5.3)
NO, that pump is designed for carbureted use. you will need a pump rated for EFI use such as our 12-920. Thx J
@@HolleyPerformance what's recommended for turbo ls swap that's carbed?
So, I run the red 97gph pump. Does it mean I dont need a regulator? The preowner installed a regulator anyway. But how to ensure my edelbrock will get constant 5psi without a regulator than? Thanks for your support.
You don't need a regulator for holley red vane style, it is limited to 7 psi.
@@harmankardon478 In theory you are right. But I also have vapor lock issues so I will need a return line too. So, I will install a bypass reg. and as a benefit I will know the pressure on the line too.
if you know why are you asking?@@fuelbasti
Is it possible to damage an in-line fuel pump by using it with water?
Yes it is possible, water when in it comes in contact with oxygen (air) can cause rust and corrosion damaging pump internals. Water does not have the lubrication properties that fuel does increasing wear and heat. A small amount of water is present in most all fuels, especially fuels with ethanol added.
Can the holley red pump be dead headed to feed a carburetor?
Yes, Our red pump has an internal pressure relief valve with a maximum pressure of 7psi for carburetors and is designed for use without an external regulator. Thx J

i need a fuel pump for a 2000 frontier
I have an 06 Z71 flex fuel Avalanche and I’ve installed an GM Performance 6.2 ls3 rated at around 515 hp, I’ve somewhat recently, about 5 or 6 months ago, started running e85, by the way it’s my daily driver. Within the last 8 weeks I’ve replaced the fuel pump twice and I think the pump I just put in is exhibiting the same pre failure symptoms. It’s an intake pump in a return less system. I’d ultimately like to add some more performance adders such as forced induction but obviously need to get this issue resolved first. I’ve been looking at retro fitting an after market in tank pump and filter do you have any suggestions? Thanks
Can you tell me more about your current set-up? What pump are you currently using, what size fuel line/hose? what pressure does your system need? When you say returnless, you have no regulator what so ever (in tank or external)? Are you using Pulse width modulation? Thx J
HolleyPerformance,
Thanks for the quick response!
It’s the factory configuration currently, in tank pump, regulator, filter unit, 3/8” supply line. It does have the factory charcoal canister and evap solenoid but no return, Im not opposed to installing a return depending on the feasibility/cost. I believe it should be running at 70-75psi under load and 60-65psi at idle. I’m still getting familiar with the operating system and have a custom tune but I do believe it uses pulse with modulation.
SO it's a factory in tank fuel pump??? If so, I would check with your GM dealer and make sure that the replacement unit you are using is in fact compatible with E-85 fuel! J
HolleyPerformance,
Yes and yes, why do you ask?
To clarify, it’s a flex fuel vehicle/pump. E85, I’m not so sure.

Are you running a carburetor or EFI? Do you already have a regulator?
hi, thanks for the reply! have a 2bl carb that came stock with the 351m. freshly cleaned. I do not have a regulator
One of our Holley red pumps part # 12-801-1 should work just fine. You could also use a Mighty might pump part #12-427. Be sure to mount the electric pump as close to the fuel tank as you can ( electric pumps are better at pushing fuel than pulling) and below the lowest fuel level in the tank as possible.
Here are 2 charts to help you make an educated decision. Dont forget the filters!!

What fuel pump can I use for a 2005 GMC Sierra 5.3 v8?
Give our tech department a call for a product recommendation! -Keith
HolleyPerformance do you happen to have a number I can call?
Holley made in korea
where are Holley products manufactured?
I'm considering making a purchase but have seen some "old" companies "new" chinese made stuff and it is so poorly machined it doesn't even function correctly.
If Holley has taken this route I wont fool with it.
My husband installed a Holly electric fuel pump on our '70 Nova. The thing sounds like the car is ready to fall apart. Sometimes, it's quiet, and sometimes it super loud. It seems to be getting progressively worse. We haven't figured out a pattern as to why this is happening. Does anyone know why it sporadically sounds loud, and what can be done about it? My husband's tightened it to where it isn't rattling, so it's not that. It is mounted in back by the fuel tank. Thank you.
What part number is the pump?
I don't know. It's a Holly electric fuel pump putting out between 4 and 7 psi. The carburetor we use calls for about 5 to 5 1/2 psi. We filled the tank yesterday and the noise stopped. For now. The gas tank still had about 6 gallons of fuel in it. Hubby figured it might have gotten low enough that the fuel pump was sucking air. We're hoping that's what it is. Like I said, for now it's quiet. Thank goodness. :-)
There are several factors that are crucial when using an electric fuel pump. First the pump needs to be mounted as close to the tank as possible (elec pumps are better at pushing fuel than sucking fuel). The pump also needs to be positioned as low or lower than the lowest possible level that the fuel will be in the tank! Since it sounds like you are using the stock fuel pickup (correct me if i'm wrong) in the tank, it's a good idea to drop the tank and pull the pickup assembly out for inspection. 48 years can change a lot of things. The pick up could have been damaged from previous installations or even have pin holes causing fuel aeration or completely rusted off, reducing its ability to pick up fuel as low as it should be able to in the tank. replacements are inexpensive and can be found at most auto parts stores or online. thx J
Thank you so much, J, for taking the time to respond. I've passed on this information to my hubby.
If i wanted to have a math session this would not be it...
I like the t-shirt. I’m glad a woman didn’t have to do that presentation.
YOu didn't address noise.
Noise level depends on the pump mounting location, what isolation mounts are used, vehicle sound deadening, etc. Too many variables to cover! J
So many big words I can’t understand nun of this 😂
