Ford F-150 - 1997-2003 :: Gas Tank Leaking - Low Fuel Light Came On?
Jul 1, 2016
My '97 truck has over 315,000 miles on it, original fuel tank, 30.1 gallons, replaced fuel pump maybe a 9 months ago. No gas gauge problems until today. Bought gas this AM and had about 3/4 of a tank. During my drive home (56 miles round trip), noticed the gauge was read about an 1/8. Had monsoon rains today, so I wouldn't have noticed any gas pooling under the truck or a smell if it was suddenly leaking. On the was to fuel up, low fuel light came on. Bought only 5 gals of gas in case tank was leaking and I have to drop the tank. Low fuel light out after restarting the engine but the gauge reads the same, about an eighth? Diagnostic ideas? Won't really be able to examine the tank for leaks until things dry off, probably tomorrow. Diagnostics??

I have a 97 F-150 and my Radiator fluid has been leaking very bad but hasn't been taking the fluid from overflow tank. Actually the new fluid that I put in the overflow has now turned a rusty color....

2003 XL 5.3L with a leaking fuel line between the tank and filter. Mechanic says that this line is only available in a kit that includes all fuel lines for the truck. Hard to believe you can't just get the one line.

So my 7.3 started sputtering and lost power, died on the side of the road. I wasn't far from home put about 8 gallon of diesel in the tank with a couple of fuel jugs and it fired right up.
Gauge was reading 1/8 of a tank and low fuel light did not come on. (low fuel light comes on when you start) Gauge came up to about 1/2 after putting fuel in.
What happened? Gauge was always reliable and low fuel light always did work. Only work done to fuel system was had new tank straps put on a couple of months ago.

1996 F-150 5.0... So I bought this truck a couple months ago for a really good price and its my regular vehicle that I use daily. While driving I switched tanks from the front to rear and when i reached my destination i noticed that fuel spilled from the cap, I opened the cap and fuel overflowed. I've read in forums saying that its the Fuel Pressure Regulator or the Fuel Tank Selector Valve . It still drives and runs fine, but I would like to know which part its specifically causing the problem?

I have a leak in my rear fuel tank, the front tank has been blocked off and is not used, The leak is at the seam of the two part tank, once removed is there a way to seal this? or should I just replace it?

So my truck felt gutless somtimes, wouldn't start Every couple days , and Fuel gauge stops at half tank won't show full, so I went n bought a new fuel pump..... Well shoot nothing changed . I guess my next move is pull the dash off n fix gauge? It used to be a reliable truck . Now Im not comfortable to let wife drive it . I also pulled the chip to see if that had to do with not starting, also theft light blinks normal. I'm going to get some connector grease n redo all of my wires to c if there's just connection issues.

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.

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.

I have a 1997 Subaru Legacy Wagon and the fuel tank is leaking on the top. I have taken it to the local dealer to replacing the tank. It seems that you have to take out the exhaust system , then the rear drive train to even get to the tank. It was not a problem for quite awhile but now the check engine light is on and it won't pass inspection. Is there a way I can fix this without taking out the tank?

I have a 2006 F250 c/c LB and I am curious, how much fuel is left in the tank when the low fuel light comes on?

My '10 Golf TDI started leaking gasoline this morning, found smallish puddle in the garage. Looked underneath and there was definitely fuel on the underside of the tank. Moved the car into the driveway so the leaking fuel can evaporate.
Not sure what happened. I did hit something on the highway yesterday, a piece of tire from a semi went underneath the car. Of course it's been really hot 100+ deg lately. Maybe a fitting has come loose?
I'm not going to risk driving it, but can't do anything about it until monday. I'll call the shop and see what they recommend, tow or drive.

I have a 2004 F150 XLT 5.4 L 79,000 miles. Yesterday i was driving home turned a corner and the low fuel light came on and the fuel gauge is well below empty. I had approx 1/2 tank of fuel when it happened. I have since filled tank all the way but the gauge will not move and low fuel light stays on. Everything else is working fine! I have never run the truck low enough on fuel to make the dummy light come on.....

Not my Elantra, but an '05 Santa Fe 2.7 ... I have a fuel leak from the driver's side of the tank. It has continued leaking while the vehicle has been parked with about a quarter tank of gas, even after 8 hours. I can see where it is leaking from - a quarter size depression in the tank - but I think this is some sort of plastic pan, not the tank itself.
Is there is a plastic pan under the tank?
If so, does it cover just the bottom half?
If it is a plastic pan, is the tank itself plastic or metal?
If it is plastic I don't see how it could develop a leak, so is it possible for the leak to be at the top of the tank due to a fuel line problem (maybe some mysterious syphon condition)?
I searched the forum and leaking fuel tanks don't seem to be a common problem. My usual parts store doesn't even have a listing for a replacement fuel tank.

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.

Check engine light popped on (first time ever) at 76,000 miles. Had my brother read the code with this engine diagnostic tool and it said "Fuel Cap". No big deal...
Take it to Hyundai, nope, not fuel cap... it's an Emissions/Evap control valve leaking above the fuel tank somewhere.

I got a call from my inlaws saying their truck wouldn't start. Well apparently it had been chugging the day before keep in mind the low fuel light is always on , and they made it home but it stalled and wouldn't start again ran out of gas i imagine he added gas but still nothing , I know with some of these trucks they have a maxi in the tank but would it clog to the point it wont allow fuel to pass ? how do you bring up dash engine fault codes ...

So I pulled into my driveway yesterday about 5 minutes after my low fuel light came on and as I was making the final turn around my house the engine cut off. Luckily I was able to park in it's normal spot before coming to a halt.
Anyway at first I though "out of gas" even though I knew I'd driven further with the light on. After putting in 3 gallons still no luck. I noticed with the key on no noise from the fuel pump so I checked the fuse and relay both were fine. I then checked all the other fuses and noticed the large 30amp PCM fuse under the hood was blown.
When I replaced it, it blew instantly. I was able to hear the fuel pump come on for a brief second before it blew out. Unsure if the two were related I then pulled the Fuel Pump fuse and replaced the PCM fuse one more time and again it blew. The motor cranks over but won't fire (not getting fuel.) Where I can start to correct the issue.

2001 F150 5.4 Auto ... Truck was running excellent. Engine light and overdrive light begins to blink and it acts like its running out of fuel or water in gas. Baring made it home. Cleared the code and it comes back. Transmission seems fine.

I got a new to me 1998 F150 a week or so ago but it got parked quickly when I realize the gas tank strap was broken. I took it to a dealer today and they replaced the strap.

My 99 F150 with 200K miles, but running like new, dropped the rusted front gas tank today. I removed it and would like to use the rear tank which is almost new - put in last year.
Is it possible to make it go with only the rear tank? This is only a plow truck (no plates or insurance) just used in my driveway! Top speed for me 4 MPH. hOW TO BE able to get it to run with only rear tank?
