Ford Fuel System :: Small Leak Where Filler Neck Ties Into Rubber Hose That Runs Into Fuel Tank

I recently purchased a used 1999 F250 Super Duty with about 150k miles on it. The truck runs great and I have no complaints but there are a few things that need to be taken care of. It looks like there is a very small fuel leak where the filler neck ties into the rubber hose that runs into the fuel tank. There is a thin film of diesel along the side of the tank, on the leaf spring, the air bag and various other places. Nothing is dripping. I want to drop the tank and replace the hose. The Haynes manual says to depressurize the whole fuel system--is this really necessary if I don't plan on doing anything to the system aside from dropping the tank?

Ford Fuel System :: 1976 F150 - Fuel Draining All The Way Back To Tank

My vehicle:
1976 F150 2wd Extended cab
390 4bbl
c6 transmission
4BBL Edlebrock Carb
Dual fuel tanks, only rear main tank connected

My problem: For the first year I owned the truck, everything ran fine and it started up really quickly even after it sat for a few days or a few weeks. I have since, for about the last year or so, had to crank it for 30-45 seconds to get it to start. This all started around the time my fuel pump went out. I replaced it with an Airtex fuel pump from Autozone. I also installed a glass in line filter before the carb in front of the distributor.

I noticed that after about 4-6 hours, the fuel had drained out of the filter and that's when I would have to crank it forever to get it going. It also seems like there is no fuel in the carb as it doesn't even try to start when it first gets cranked. I thought this was a bad pump, so I bought a new one last week and tried it again. Sure enough after about 4-6 hours, everything is empty again and it takes forever to start it. So it's not a bad pump, or so I think.

The other day I backed it into my driveway and left it, something I never do. I checked about 4 days later and there was still fuel in the filter. This makes me think that gravity is making it drain back to the tank.

Is there something that would cause this? Also I have found a one way fuel check valve online that is supposed to remedy this type of problem. Do they work for this situation? Or is there something else I should be doing to fix this? It has taken a bit of a toll on my starting system having to crank so long all the time. I have so far had to replace my starter, starter solenoid, and all the battery cables, starter cable, terminals, etc. due to excessive wear.

The valve I found is here : [URL] .....

Ford F-150 - 1997-2003 :: Fuel Filler Neck Rusted?

The fuel filler neck on my truck is very rusted. I'm very concerned because if it gets a hole in it I think I wouldn't be able to put gas in the tank. It's completely exposed to anything that the tire throws at it. Is there any way to protect it?

Ford Excursion :: Fuel Filler Neck Hose Leaking

After my accident this summer with the Ex and TT, I have a fuel leak. It appears to be coming from the hoses between the filler neck and tank.

The part # from Ford for the neck and hoses is YC3Z-9034-AA. This part is no longer available! Even NAPA the go to place and pay thru the nose for shows it as obsolete from their vendor.

I am seeing RED at this since I had zero leaks until the body shop dropped the tank to replace the hitch. The BS and INS co told me prove it was not a dry rotted house and they would pay for it. What to do for the hoses?

Golf IV / Jetta IV :: Filler Neck Seems To Back Up With Fuel / Shuts Off The Pump

Ever since i have had my car i have had a slight problem re-fueling. The pressure inside the tank doesn't seem to vent correctly and the filler neck seems to back up with fuel and shuts off the pump (too much back pressure) when i'm only ~30% full. I can elevate the problem by re-fuelling slow enough so that the pressure can vent back through the filler neck but it gets rather annoying to sit at the pump for 10 minutes re-fueling.

Ford Fuel System :: 1986 F150 - Engine Is Running On 4 Cylinders 1 / 4 / 5 And 8

What to do next. Engine is running on 4 cylinders, #1, 4, 5, 8. Had a mice nest on top of injector #2. Removed mice nest. The mice had chewed through wire for #2 injector and caused bear lead rubbing on the block. One lead rubbed through. Repaired, splised in a wire. Also changed rotor, rotor cap, all sparkplug leads and plugs.

Troubleshooting.
Compression on all 8 cylinders measured to be above 160 psi.
There is spark to all 8 cylinders, including the other 4 cylinders, 2, 3, 6, 7 that is nor developing power.

Fuel rail pressure is 35 psi on idle and spikes to 43 when reving the engine.

The fuel injector resistance all all measured injectors are the same (about 14.8 Ohm). Measured injector # 1, 2, 5, 6, 7, 8. Injector # 3 and 4 is hidden and require too much disassembly. Visual inspection deems wire for #3 and 4 injector to be ok on top of block.

Electric impulse (tested while engine was running) to injector # 1, 5 and 8 are ok, used test lamp to see that there are electric impulse to the injectors. Injector #2, 6 and 7 does not have any electric impulse. Unable to check electric impulse to # 3 and 4. However cylinder #4 develops power. Used moving the sparkplug wire for cylinder #4 to verify that is is developing power.

What would my next step be? Where should i look next?

1. Where is the control module and is it likely to fire to only 4 cylinders
2. Could it be an wire in the pickup element, under the distributor. All wires seem intact.

Ford Fuel System :: 1986 F150 Idling Rough / Leaking Injectors?

I have an 86 F150 that is idling rough. It used to cut out on me until I replaced the fuel pressure regulator. I have read in other posts that the problem for my rough idle could be leaking injectors. When I replaced the regulator I found a bad injector. My question is that if I check my fuel pressure, with the new regulator, would the only way I would lose pressure be that my injectors are leaking?

Ford Fuel System :: 1987 F150 - Leaking Started From The Rear Tank

1987 f150 302 4spd 4x4. When I bought the truck 4 years and 12K miles ago the orig owner had just installed a new front pump (in tank) and new switch thing on the frame rail. He said shortly after that the rear pump stopped working so he just ran off of the front tank. That's what I've been doing also except as of the last few months it has started to leak from the rear tank (I don't ever put gas in it and was empty when I bought it) and dies periodically from time to time? Where the leak could be coming from. I do suspect the dying has to do with the leak though.

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 :: 1989 F150 - Hot 28 Psi Fuel Pressure Shuts Off?

for the past week we have been trying to figure out what is wrong with our truck. We recently bought it and it ran fine. Then got in a minor accident just a fender bender and it started acting up so I got towed to garage. First it would run when cold, but when hot fuel pressure would drop to 28 psi.

So I put new fuel pump, it started but still did the same thing hot 28 psi fuel pressure shuts off. So I put regulator on it, then had 0 fuel pressure won't even start. So got a another regulator thinking I got a bad one, still 0. Checked relay, there fine. I'm gonna check lines and see where fuel stops at but everything is new on it.

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?
