1996 Ford F-150 Owner Comments

problem #4

F-150 XLT 5.0L V8

  • Automatic transmission
  • 161,380 miles


Ford mechanic told me it could be check valve or fuel pump that is cause for back tank fuel to spill into front tank, causing an over-fill or leak to happen.

When the rear tank is filled with any quantity of fuel, from 1 gallon to completely full, it pumps or cross fills the front tank to over capacity, which makes the front tank spill gas from the fueling neck/gas cap, in large quantities until the rear tank has completely emptied out. (At stop lights, intersections, idling, warming up, get the picture?) It stops after the engine has been turned off. If the front tank has gas in it of any amount and I leave the rear tank empty, my truck has a very rough idle. When I am running off the rear tank the rough idle dissappears. I replaced the fuel filter with no change in condition. When I took my truck to our local Ford dealer and explained that my truck was pumping gas from the rear to front tank, the technician quickly informed me that it was not possible, and to get off the drugs, or get better ones!!! I know this is a problem in earlier F150 trucks and there have been recalls on F150 trucks with very simular to identical problems as mine. Whats up Ford? Time to man up and fix the fuel issues or I'm buying a different make of vehicle next time! Any advice on how to stop my fuel problems would be greatly appreciated. Needless to say I won't be returning to my local Ford dealer for help.

This is a really big pain in the ass. There is only a return line going to the front tank. I did not know this and filled both tanks. I was using the rear first so after a while of driving fuel started pouring out of front tank because it was being over filled by the excess not being used in the rear. For drivers that only have the rear tank working this is a killer because you are filling a tank with gas that doesn't even work! Not to mention the waste of money on gas and if you don't siphon it out from the front tank then it starts leaking. This could cause your vehicle to catch fire, the gas could ruin your paint, you are throwing money out of the window, and you are constantly having to siphon gas from the front tank.

F-150 5.0L

The straps on1996 f-150 front fuel tank literally broke and fuel tank fell off. Lucky for me I was in my own gravel driveway. The front fell off ,and if I had been going down the road I likely would have blown up or minimally went ass over tea kettle. Either way, I would have gotten hurt pretty bad or charred real good. Fuel pump and tank leaking in 95 with dual tanks also. Engine blew at 70,000. Bunch a bull. Engine blew in 89 also with same , 70, 000 miles. He. Could be a thing. Nonetheless, my next truck will be a Bob or Phil or Tom, anything but a ford. I've been bent over enough . Shifty design all the way too. Brakes went and buried inside frame rails. Lines that is. Just bad mojo!
