It definitely has something to do with the fuel flow from the front tank. It may be the fuel pump again, the older F-150's with two tanks soemtimes have problems with the fuel pumps because of the extra pull from two tanks, and the switching between them.

You could check the fuel filter (assuming there are two fuel filters, one for each tank)...but otherwise it sounds like a fuel pump problem, or possibly an obstruction in the switching mechanism for the two tanks, or an obstruction in the line itself. Hope that helps!

I have a 1997 F250, 460, Truck will not run on front tank, if I switch to the rear it runs great. If The truck is running on the rear and I switch to the front tank, the truck dies. Ideas?

Have the fuel pressure checked on the front pump when this happens. You either have a defective fuel pump, a defective switch over poppet valve or a defective dash fuel tank selection valve. switch.

I have a 4 wd 2002 tahoe. One minute the truck was running fine then all the sudden while trying to accelerate the truck fell flat on its face, sputtered then died.The truck then had to sit for a few min....

I might look into the anti theft security system. These can turn off starters and/or injectors when not working properly. Do you see a light on the dash that says SECURITY when this happens? If so , check out this link.

My 89 Ford F150 dies when I switch fuel tanks from rear to front tank,and now leaks gas some where in the area of the side front tank when Iam running on the rear tank.Where do I begin?

Does you truck restart after dying and then run ok or does it stay dead until switching back to the rear tank?
It could be that the front tank has a leak in the suction line which will leak when not in use and **** air when you switch to it.
A suction air leak could be the reason for it dying when switching tanks

Not getting fuel. told not to use the rear tank

I had an 86 F150 with dual tanks, it had a similar problem. The problem ended up being the switcher valve (switches from one fuel tank to the other). Mine was electrically controlled and would switch from rear tank to front tank, but (front tank also had a leak) would not switch back to rear tank. I found out that my switcher valve (after I tried rebuilding the switcher valve myself, and determined that it was not repairable and needed replacement) was defective. They are also not cheap-about 10 years ago it was about $150! Don't know if yours is the same model, but I found the easiest thing for me to do then was remove the front tank, since it leaked (metal mounting straps worn through in spot where insulation came out sideways), and remove the switcher valve. I always left my tank switch set to REAR (dont know if anything would have happened if I had moved it to FRONT anyway, with valve and tank gone) and it always worked fine from then on out.

What you need to do is probably a 2 man job: Have someone inside the cab have ignition on and work the switch from one tank to the other, while you are underneath the truck at the switcher valve. Your job would be to determine if the valve actually works both ways, or just one way, or not at all.

Also there are fuel filters in several places: there is one in the switcher valve, further up along the frame toward the engine, and should be one somewhere on the engine, too. Also each tank should have an in tank pump. Several places to check, it's a big job, its messy, gasoline is toxic, not to mention explosive. Wish I had better news for you.

Hope I've been helpful.

Ford Dual Gas Tank problem, Rear tank Always full.

This is a common problem. On the driver's side frame rail is a large black plastic assembly that the fuel lines connect to. This a fuel switching valve what usually happens is the valve goes bad and the fuel gets pumped from one tank to the other
