Trying to find fuel injection. Bought new battery and the toyota dolphin RV 1988 engine clicks. But no fuel coming to the engine. Would like to clean the fuel as it has been a couple of months since we have turned it on. Is it under the motor?
I have a P30 Chevy with a 7.4L 454. Where the fuel line comes up to the carb is where I'm having a leak. BEFORE the solid metal line comes up to the carb. Hopefully it is just a hose clamp type that needs tightening to the solid line. Great video! David 🚀
Ok mine doesn't look like that. I have the cylinder in front of it but not behind it. Is that something you put in to bridge the connection? Because on the oil sender or whatever it is I just described, it was a 2 wire harness connector which I'm assuming has something to do with killing the fuel or something and the other is what I think goes to oil gauge. I really need to figure this out I'm not getting fuel to my mechanical pump
try re-adjusting rhe carb screws. I'm having a similar situation. I domt every form battery, starter, voltage regulator, alternator. it was getting easier to turn over after replacing all those parts until recently. a few days ago, I discovered 2 cracked hoses that run to some sort of a filter underneath, which theirs 2 of them. I also had a 3rd hose air hose that must have fallen off. I think that 3rd hose was the cule prit. not to mention the fuel pump has already been replaced about 2 Years ago including the carburetor has been rebuilt and the rv has gone much of anywhere but around town for running a few close by errands and to test its limits. 1978 Dodge Sportscoach 440, b300
could be. also can be the fuel pump regulator that is AFTER the electric pump. it regulates the pressure going to the mechanical pump. if ur mechanical pump is NOT new, then replace it no matter what. it's cheap.
My 1982 Chevy Motor home was starting and running last month. Now when I turn the key on the fuel pump in the back just keeps running and no start. It is not building up pressure as it usually would stop. Starting fluid will Start the eng. but then it dies. I am assuming the the pump may be bad. It does have fuel in the tank. I guess I will disconnect the fuel hose from the carb and see it it pumps fuel. But I don't think it is. Is this a common thing with tank fuel pumps? Mine is on the outside of the tank.
@rvlifewithdjdarren but what year, model,etc... was in your video? Someone else posed the same question, n you did not answer. I just came across your video so, have no history on you or what vehicles you are showing/do work on. Please provide that type of info in your videos n in their respective tag/info line. Otherwise, fairly good video. Thank you. 😊 ✌️
Im asking questions for a 1995 tiffin allegro. I purchased it not running for about 6 years with fuel left in it. Im wondering if what i thought was a quick fix might be turning into a magilla?
Ford E350 Econoline RV. 351 engine, 1987 carburetor. Been sitting for awhile, will not start. If you put gas in carburetor it will run but then it stalls out. Do you think this is the same issue?
@@brianharrington5176 if you click on my page I showed how to make a d.i.y fuel tank with external fuel pump maybe it will help ( I have a 350 aswell )
I have a 350/460 ford 1990 dolphin rv does it has two feul pumps and where is the feul relay located at all my feul systems have been replaced. But no pressure it was running fine then a few weeks ago it wud stop now now pressuer what so ever please respond asap thanks man
you need to check to see that electric pump is coming on. you can hear it. also problem can be fuel pump REGULATOR which regulates pressure AFTER the electric fuel pump.
@@jackdeans1045 is that up front? I’m trying it figure out if my 83 Ford motorhome has a pump like that on the front it’s not getting fuel up to the carburetor so I’m wondering if it could be one of those
@@adamwiley350 I am working on an 85 Ford. I have the same situation on an 85 Ford 460. I have not been able to find a mechanical fuel pump. I see 2 fuel lines from the tank. One supply and one return. Usually indicates electric only pump. My camper has sat stored inside for over 10 years. I'm pretty sure its the fuel pump, but it would be nice to have an electrical diagram to make sure its getting power. I have a manual on order. All that said, I would still like to benefit from your experience.
for sure its carbonated not fuel injected, most likely ford 460ci engine due to the motorcraft looking spark plug wires and the angle the spark plug is oriented (GM big block engines are usually orangish-red in paint color however the later small block chevy can also be painted blue) blue engine paint and shape of valve cover! Also, the location of ford"s rear electric fuel pump and at least 1 fuel filter for this vintage is on drivers side frame rail maybe 5 or 8 feet forward of the rear wheels. Crawl underneath (with the wheels securely blocked/ emergency brake on) with a good flashlight while laying on your back, position yourself forward of rear wheels and you'll see electric fuel pump and fuel filter. Pump and filter are fastened to the inside of the frame rail. The electric pump is designed to "push" or "lift" fuel to the engine where the 2nd mechanical fuel pump and it's diaphragm "pulls" fuel the rest of the way into carburetors float bowls. Hope that wasn't too confusing.
There's a line hang from the tank for mine but I need to find the Mechanical fuel pump because mine was running. But the line is distinctly and I'm looking for the mechanical fuel. Pump to connect to it like you say it right. Doesn't allow gold straight to the mechanical fuel pump from the back
The RangersEdge I had the same question, not enough info to be truly helpful.. I have a 79 Winnebago Brave I think the mechanical fuel pump split a diaphragm and I need to replace it. Where is it?!
Sean Lane Im sorry, I dont know about Winnebago. I was here because Im trying to restore a 1989 Toyota Dolphin RV. But it has EFI, not a carb so this video was useless to me.
The reason it won't start after sitting is because the carburetor bowl leaks off. If it is a carbureted engine. If so, rebuild the carb .You are not fixing anything by using these shade tree tactics.

What make year and model is this for. Thanks

hey Dave, I have the same set up. how about letting me know where I can get the fuel pump for this?
That was a great video. 1990 Las brisas dolphin. Wants to turn over but not.

I cant find the little oil thing to I jump. 1990 Las Brisas dolphin sat since2006 in storage please help!?!?!?
where is this oil sending unit located
Could anyone please show me the fuel schematic from tank to pump to carb there are two gas tanks drawn out for the 1986 Ford lenda moterhome
What year and make RV was that?
Where do you put gas in it I’m trying figure it out
So mine only has the thing right above what you're showing
Thank you.
I need help my fuel pump push pin won't fall out on my 454 RV motor. I don't know what year it is and it's in another truck.
put some grease on the end of it stick it back in grease hold it in place

I'm changed the back fuel pump..time to do the mechanical one..my starts but will die on me..
My starts up..runs I hear a pssssst sound and dies
And of course this video applies to all RVs, all years, all engines for every brand ever made.
😆 😉 my thoughts, too (sarcasm). 😜
✌️
Good video jack, question, where is the back pump? Can you make a video showing the back one? Thanks
In the gas tank
Will this apply to a 1978 Southwind Class A RV?
it should. no brainer to replace the mechanical fuel pump & keep that thing new.

I wonder if mines have a rear pump
most RV's do. they have a electric fuel pump that feeds into a fuel pressure regulator, then on to the mechanical fuel pump on the motor.
I have a 350/460 ford 1990 dolphin rv does it has two feul pumps and where is the feul relay located at all my feul systems have been replaced. But no pressure it was running fine then a few weeks ago it wud stop now now pressuer what so ever please respond asap thanks man
you need to check to see that electric pump is coming on. you can hear it. also problem can be fuel pump REGULATOR which regulates pressure AFTER the electric fuel pump.
What year?
Yeah
are you under the RV, looking under the hood? where is this oil pressure switch exactly?
The bottom of the motor. I'm on my back under the motor looking up.

If the diaphragm in the pump is good, it won’t hesitate for very long
How hard is to fix carburetor
