Ford - Club :: 1991 - Fuel Is Coming Out Of Front Tank Fill Spout When Engine Running
Jan 14, 2016
I am having an issue with by club wagon. This vehicle has dual tanks. The front tank doesn't work (and never has since I purchased it a couple of years ago....bad fuel pump I am guessing}.
A couple of months ago the fuel pump went out on the rear tank and I had it replaced. I now have a peculiar problem. Fuel is coming out of the front tank fill spout when the engine is running. There seems to be a tremendous amount of pressure building up in the front tank...even though I am not using it.
I would seem as though fuel is being pumped out of the rear tank and into the front tank to a certain pressure point, and then on to the engine. One solution would seem to be to remove the front tank completely from the system, but I don't know how to do that, or if it should be done. After driving and coming to a stop, fuel is pouring out through the gas cap on the front tank. I. Don't need to use the front tank as I am just using this as a work truck.

02 limited with 116k v8. I changed the oil in the truck and noticed a white-gray gunk inside the fill spout...... I wiped it all out but I am trying to figure out what it was?

I have a 1986 F150 6 cyl, dual tanks, no AC, manual fuel pump. Just recently, I have been having issues with the tanks. At first it seemed like the back tank was siphoning from the front tank. Now I have fuel coming out of my front tank filler neck. When I open the back tank gas cap, there is enough pressure to spray me with gasoline. I am not familiar with the fuel delivery system of my truck ...

The ole 5.4l hit a snag today. I was on my way to fill her up and she started sputtering and damn near died! i filled her up and it was like nothing ever happened. Took her to AutoZone and the diagnosis was a Fuel Tank Pressure Sensor.
I have a connection with Bumper-to-Bumper to get the part for cheap but I'm not sure if i want to dive into either moving the bed or dropping the tank. I'd prefer to move the bed.

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?

I have an 04 Elantra GT. My gas gauge is showing full but the car is running out of gas. I try to fill the tank and I get the annoying click and after trying for a few, gas comes up the filler and overflow tube and makes a mess. At the same time, I was getting a P0449 code. I got an evap canister from the junkyard and that seems to have gone away.
Tried diagnosis but dropping the fuel tank to access the lines. When I jack the tank back up into position, you can hear gurgling sounds and as if the gas is coming up the fill tube. I also opened the access panel under the seat to see the pump assembly and when I removed the 8mm bolts, gas came pouring out. There was definitively gas in there. Checked the float on the pump assembly and it moved?
There is also something at the fuel neck at the top. Don't know what it is and if that could also be part of the problem.

2007 Pacifica with 4.0 will not fill unless you dribble the fuel into the tank. I have cleared the vent hose and know it is clean. Do I need to change the Carbon Filter and Solenoid/Evaporation Valve on the Front of the Carbon Filter?

I have a 2007 Santa Fe. If I fill the tank to full, or close to full I will have a fuel smell in the car until the tank runs under 3/4. If I keep it under 3/4 I usally do not get the smell in the car.
The dealer could not figure it out and I still have this issue. It seems the smell is more in the front of the cabin then the rear. It just could seem that way since the smell is very strong. I have to park the car with the windows open.
There are no fuel leaks, no fuel on the ground, no drips, and the no spillage when I filled the tank.

My 2003 Expedition has started spraying fuel out of the fill tube whenever I fill the tank. It started 6-8 months ago. At first, I thought that maybe it was a fluke. It kept happening. I am so tired of getting fuel all over myself and my car. Not to mention the environmental impact of the fuel spill. This isn't just a little fuel dripping out of the tank and spilling on the ground. It's a full on projectile expulsion of fuel from the tank. What's happening and what I can do to fix the problem?

From all I can see, the fuel tank capacity on my '12 should be 17.5 gallons.
As I finish up a trip with it, I know I've "pushed the envelope" as far as fuel range is according to the guage/computer. I get the warning that I need to refuel and that I have 50 miles to empty, but I've driven 40 miles into that last range before refueling, and only been able to put 14 or so gallons into the tank.
My question is: If I were to drive until it literally runs out of gas, then fill it, would the guage/computer recalibrate or do I need to install a new fuel sensor?
I get the warning as the guage indicates just under 1/4 tank remaining, and I have yet to run it until the guage indicates that it's actually on empty (family and dog are with me so risking it is currently out). I'm hoping that the guage itself knows what the real deal is and that the computer is just not with it.... OH, FWIW full is EXACTLY on the "full" line and not over as in my Kia.

I have 2007 explorer 4.6 v8. The check engine light is on, and i can only fill the gas tank about 3/4 full, after moving the gas nozzle all around and taking about 15 minutes. I read a few different things while searching. Like vapor canister need to be replaced. or the vent hose needs to be replaced.

I recently replaced my gas tank in my Sundance, it was getting very rusty around the sending unit area and was starting to leak. Everything is back together and it is running well with no leaks. The new problem that it has, when the car is running, the gas gauge shows less than empty, even though it has a considerable amount of gas in it. When I shut the car off, the gas gauge slowly moves up to where it normally would be when it would be running. Did I somehow mess up the ground or did I cross something? This is my daily beater car and need a working gauge.

The other day, my father-in-law was driving my '91 Explorer and it just died on him. I assumed that the fuel pump quit becuase it wouldn't come on when the switch was turned on. I had a brand new lying around so I dropped the tank and put it in but it still won't work. I checked the inertia switch and it wasn't tripped. There is no power coming to the new pump at all. When the switch is turned on, there is a noticeable "click" inside the engine bay. Would that be the fuel pump relay making that "click"?

I am unable to get fuel delivery from tanks to engine in normal operation. I can however get pumps working with jumper wire to them. It will start with ether but not stay running on it's own. Could this be a relay or something in tfi thing ?

I understand that filling up with gas when the car is running is not recommended. I did it once without realizing that it could cause issues. Now I am trying to determine if that action has anything to do with the CEL being on. The codes are P0442 and P0456. The codes have been cleared several times but the light pops back on after a while, anyway from one day to a week later.
Smoke test did not reveal any issues. My question is this, can filling up with the engine running cause any physical problems with any of the EVAP components? What would be the most likely problem? I plan on buying a new gas cap, since it is cheap. I do not wish to spend a lot fixing this problem.

I have a 85 e-250 351 4 barrel with two tanks. My tank selector switch was bad, and I have no clue how long the gas has been in my front tank, but it is very bad. I have tried to siphon it out, but for some reason it wouldn't start flowing, and I tried to drain it from behind the fuel tank selector valve, but it wouldn't flow. I figure i need to pump it out, so my question is what is the best method to pump out 25 gallons of bad gas?

Our 2012 camry se had a problem with the fuel pump running when the engine was off. Several hours after we came home I went into the garage for something and heard a humming noise. First thought was a distant neighbor using a leaf blower, then realized it was coming from the rear of car. definitely coming from gas tank area. Turned key on, then off and noise was gone.

A while ago, the front (mid) tank on my '97 F350 4x4 stopped functioning. I thought that because when I'd switch to the front tank, it died. I decided to put it off and use the rear tank cos it worked.
Today I accidentally bumped the fuel tank switch to front, and it was working! Truck didn't die then I noticed the fuel gauge pegged past full. Having tested older trucks by grounding out the gauge sending unit wire, it would peg past full. So I think I had an electrical issue that caused the front fuel pump to stop working in the first place, not that it went bad as I originally thought...
So, does that mean the front fuel pump had been working all this time, just not grounded? Does the front fuel pump ground itself on the tank or is there a grounding point? I currently can't find any way to see how it was grounded, as it's crusty and all.

How/why does fuel transfer from front tank to rear tank ? I put 6 gallons in front, drove about 5 miles, parked over night, all fuel now in rear tank which was empty.
