My truck is a 1990 Ford F150. It seems like when I let it sit for a few min that the gas just drains back into the tank and there for it wont start up that fast, it takes a while to get it going but when I shut it off and start it back up its like a new truck. It starts right up!!! Any tips on what might be wrong, maybe the gas cap is letting pressure out? Im 17 and my dad knows alot about trucks but he cant tell whats wrong.
View 1 RepliesFord Fuel System :: 1990 Aerostar - Gas Dripping Onto Exhaust At Y-joint And Evaporating
I have a 1990 Aerostar 4WD, 4L, with about 120k miles. About 6 months ago I started my van and noticed under it that gas was dripping onto the exhaust at the Y-joint and evaporating. I shut off the van and drove another car to work. That evening with fire extinguisher at hand I drove my car up on ramps and quickly got under it looking for the leak. NOTHING. 6 months later...yesterday. I drove for a few blocks from home and notice heavy gas fumes etc. Stopped the van and again gas was dripping onto the Y-pipe joint.
This was an explosive situation... I pulled off the doghouse cover and saw, smelled and touched gas friom on the right top of the engine near the back. My questions are: What could randomly be leaking at this location and is it fixable without pulling the engine. I pushed the van to a secure location and am afraid to turn it on. Maybe I will drain the gas tank before then. I am just now trying to find the schematics for the fuel line delivery stuff. Where to go for a manual.
Ford Ranger / B-Series :: 1990 - Broken Fuel Line At Fuel Pressure Regulator?
I have a 1990 Ranger with a 4.0L that I just changer the intake gasket on. I broke the fuel line at the Fuel Pressure Regulator. Cant seem to find one anywhere. It is a nylon inside/rubber outside with a cloth mesh and quick connect fitting line. Where to get one? Can I hose clamp it the FPR by cutting off the connector that broke?
View 1 RepliesFord 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).
Ford 6.7L Power Stroke Diesel :: Fuel Tank Leaking After Shutoff Valve Closed - Overflow?
I am scheduled to leave on a trip in the morning. I have installed an 85 gallon in bed auxillary fuel tank. I plumbed it in as per the instructions and the same as the last two I had in other trucks. After install I pumped 25 gallons in the aux to see how it worked. Every thing worked right. So yesterday I filled both tanks to the top and left the shutoff between them open.
This morning I noticed a puddle of diesel on the shop floor. Wiped it up and left for the golf course. Got home and found another puddle. I have closed the shut-off valve but it still seems to be leaking. It is not the plumbing I installed. It's hard to tell because I have a protector around the tank but it seems the leak is coming from the top. I just took a short run down the highway and reparked it. I have a can't miss appointment so when I get back I'll see how much has leaked.
Is there some kind of overflow on top the tank? Everything is dry where the aux tank is plumbed in and the air pipe seems to be fine. If the leak stops with the shutoff closed then I'm just gonna head out but if not then I'm gonna take down the shield and see what I can find, but I'd sure rather not.
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 :: 4180c - Fuel Coming Out Of Primary Vent Tube
I have a F-250 4WD with 7.5L which has a MC/Holley 4180c sitting on top. It was getting very poor mpg (like 5-6 miles/gal) and then was getting harder and harder to start. This progressed rather quickly to not starting with fuel coming out of the primary vent tube. I suspect it has to do with the primary float stuck open. I was considering rebuilding the carburetor. Is this over reaction prematurely or is there something like float adjustment that may rectify all of the symptoms described. If a rebuild is in order what is the information I would need to ensure getting the correct rebuild kit. Info that I have so far from research is it is Motorcraft ID #E5HE-9510-MC.
View 6 RepliesFord Fuel System :: Stumble And Die After A Short Highway Run At 70 MPH / Fuel Injection Flooding Out?
What would make a FI engine act like its flooding out and dying after a short run on the freeway?
Details:
1994 F-350 351W (just overhauled this winter)
has new TPS, ICM(?).
Dual exhaust dumps right before the tires
new filters in tanks, new fuel filter on frame rail
All fuel lines have been opened and blown out from the tank to the engine compartment fitting near firewall.
Fuel pumps hold good pressure when tested.
Symptoms:
smells like its running rich most all the time
after a short hiway run @ 70MPH it will stumble and die when returning to surface streets.
fuel smell near engine sometimes, but no obvious puddles or leaks anywhere.
May be related?:
When on a longer highway run, I can't use the FWD tank for a long period without the engine stumbling and cutting out or popping at times. But I can swap to the rear tank for a bit then run the FWD tank again for a while. driving up hills it seems to be worse, but I'm in the panhandle of TX right now..good grief!
I am having to drive this truck for work long distances. While I dont expect a vast fuel range, it would be nice if I could go a couple hundred miles on 20 gallons of gas....
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 :: 1995 - Stalls - Now Stop Moving - Fuel Filter?
I have a 95 F150 4x4 reg cab long box with a 302 V8 and dual tanks... I was driving around yesterday when my truck started to lung and then the motor stalled... when I stopped moving I tried starting the truck and it started with no problem, so as i kept on my way, about 5 minutes later the same thing happened and it stalled again, (I have an automatic by the way). but this time before it stopped moving i pump the gas a few times and it fired back up and then stalled again... i switched from my front take to by back maybe thinking it could me my fuel pump in the tank but it did the same thing again about same time later... Would it be my fuel filter on the frame (like in line fuel filter) or why is it doing that? its EFI by the way.
View 14 RepliesFord 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 Fuel System :: Changed Fuel Filter Now Just Cranks But Won't Fire / Start
2002 E-250 with the 4.6 V-6. Pulled the 30 amp fuse, replaced the fuel filter, replaced the fuse, now the truck wont start. Checked the fuse and the kill switch under the passenger kick cover, all ok. Cranks and cranks but wont fire. No problem prior to changing the filter. Even swithed out the relay with another, no luck.

View 1 RepliesFord 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.
