Ford Fuel System :: E350 - Fuel Tank / Pump Noise After Cutoff

This van has had a couple of fuel pumps, no surprise there, and i need to look through my paperwork and find out how many miles the current one has on it, but it has the STRANGEST habit I've ever had on any vehicle. Starts fine, runs fine, no fuel pump noise when van is running, and when you turn it off, the fuel pump creeks on and off for several minutes.

I mean a strange creaking noise almost like a shorted electrical device or a vehicle's brakes when you park it on a hill and the breaks creak as it settles into place. I'm probably doing a lousy job of describing this but i don't know how else to describe it!

ALSO, if you lay under the van and wait til it stops creaking, you can tap the bottom of the tank and it will creak for a few more seconds. You can tap repeatedly and make it creak more. Is it about to explode? Can i trust it on a road trip?

Ford Fuel System :: 1991 F250 XLT - Fuel Pump Will Not Stop Running

I just bought another 1991 Ford. This one is a 1/2 ton XLT Lariet with the 302 and for the first time I own a short bed. I also have a 1991 F-250 XLT with a 460 and a 8' bed.

Here is the problem, ( I think) it will not run or at least not for long. The fuel pump, which I am guessing is in the rear tank will not stop running. On the F-250 the pump stops running after a few seconds after I turn on the key.

Where should I start to find out my problem with the fuel system?

Ford Fuel System :: 1979 F150 - Fuel Pump Leaking From Side?

I've had a fuel leak near the pump of my 79 F150 with a 400 for some time. I didn't know exactly where it was coiming from, but fuel was being sprayed on to the oil filter from something near the pump. I assumed it was the steel line, and that it had rusted through or cracked, and was going to replace it when I had a chance. I was poking around today though, and realized that the fuel was not leaking from the line, but from a hole in the side of the mechanical pump.

For someone who knows what these pumps look like, there is a horizontal cylindrical bump out near the top of the pump, on the side of the pump that is away from the engine. The fuel is spraying in a mist out of one side of that. To me, it always seemed to be a screw channel, but I didn't think the pump was 2 halves put together? Need to know more about my pump, what that bumped out section is, or why/how fuel could be spraying out of it.

Ford Fuel System :: 1987 F150 Fuel Pump Runs After Key Is Off?

Why the frame mounted fuel pump might run after the key is turned off? Then when you turn the key on it may or not run. If it does run it keeps running. shouldn't this shut off after pressurizing the line? is their a pressure switch in the pump that's failing? This has the 3 pump system...

Ford Fuel System :: 1987 F150 - Fuel Pump Keep Running Even When Key Is Off

I have an 87 F150 4x4 4.9L EFI with a single tank. Fuel pumps keep running even when the key is off. I tried swapping relays but the problem still exists. The engine will start and run OK for about 15 secs. then die. I installed a new low pressure pump, high pressure pump seems to be OK. I also installed new fuel filters. I dont want to just throw parts at this truck, where do I go from here?

Ford Fuel System :: Fuel Pump Runs Constantly

It started out w/ my wife swapping from the front fuel tank to the rear tank due to the fuel qty getting real low. Then the next day when I drove it I had bad fuel qty and amp meter indication, I found a blown fuse on my fuel qty/amp meter gauges. I replaced the fuse and got my indications back. Now I hear my front tank fuel pump is running constantly when selected to its position. Its now full of gas and still runs constantly. The rear tank/pump operates normal. I am wondering if I ran that pump empty and lost its prime? What is the best way to burp it?

Ford Fuel System :: No Fuel Coming From Pump Nozzle?

Working on my cousin's 84 F150 351w HO with a Holley 4180 4bbl and auto trans.

I rebuilt the carb because of sticking floats (that and it was filthy and sitting). It fired up and I drove it to my uncle's shop a ways down the road before even adjusting anything. At the shop, it fires right up, idles great and floats and idle mixture screws are now adjusted.

It has a dead spot right off of idle that's been driving me crazy, and stalls in gear if I'm not careful with the pedal.

After reading around here, I looked down the carb to make sure the fuel was squirting as soon as the throttle moved, and noticed there was NO FUEL squirting from the nozzles. So that explains the dead spot...

There was just the needle, then the nozzles, then the screw that went in, same as they came out (only cleaner). Wondering where to go from here to get these working again. Going to pull the nozzles off and see if there's anything obvious going on in there.

Ford Fuel System :: Pump Not Drawing Fuel

Ok so my son and I are new to this whole truck restoration thing, but we're eager to both learn. We recently scored a 77 F250 camper special that's sat for about 14 years. When we bought it it was running. The previous owner had done quite a bit to clean it up. When we got it to the house we drove it around a bit for fun, and parked it until we could drop the tanks to clean them out. That's done, we've replaced the fuel sensors in both tanks, the lines are clear based on us blowing air through them from the engine side back to the tank side before connecting to the tanks. The mech. fuel pump is brand new and seems to have suction when we turn the truck over. We've installed a fuel filter before the pump in an effort to filter any possible residual junk out of the lines, but we can't get fuel to the engine! (Yes we put gas in both tanks.) The truck will run when we run a line Direct from the pump to the a gas can, but not when connected to the tanks. What could we be missing?

Ford Fuel System :: Location Of Check Valve That Maintains Fuel Pressure On The System?

I have a '99 E-350 6.8L. Where is the check valve that maintains fuel pressure on the system?

I have been experiencing a starting issue when the engine is hot. Cold starts are usually fine. I've replaced the in-tank fuel pump (pump only, not the assembly) to no avail. I was out of town and didn't have access to a fuel pressure gauge when the problem started so I couldn't say what I had prior to replacing the pump. But now, with a new pump, when I check pressure, I get about 40 psi when I first cycle the key on, but it drops right back to zero as soon as the pump shuts off. If I cycle the key on a few times, sometimes I can get it to hold pressure at about 32 psi, and it starts fine. When I shut if off, it goes back to zero psi, sometimes gradually, like a bleed down, and sometimes immediately.

My conclusion from this was that the check valve was bad. I was told it was part of the in tank fuel pump assembly. Since I didn't replace the entire assembly, this made sense. So I just dropped the tank back down, but I don't see anything as part of the pump assembly that serves as a check valve. There is a rubber nipple on the end of the return line, but I don't see how that can hold any significant pressure.

So, before I go out and spend another couple hundred bucks on the complete fuel pump assembly, which apparently can't be purchased without the actual pump, I thought I'd ask. Where is the check valve that holds the pressure in the fuel system?

BTW, I also have replaced the fuel rail pressure regulator, but it made no difference (I went there first since that was much easier than dropping the fuel tank a second time).
