Do you have 2 gas tanks?

I Have a 1999 ford f150 4.6 that back fires and is just running really ruff when idling alot of nack fire a sord of like a pulse going on what is my problem?

What you have is an E4OD transmission and will work with all Ford small block engines (300, 302, 351) in F150,F250, F350 and full size Broncos from 1983-1993.

How you doing first thing you might want to check for any leaks in your lines if okay disconnect your fuel filter try to blow threw it possible clog if okay you say the pump was installed recently when you installed the pump on to the sending unit did you tighten the clamp on the hose to the pump tight and make sure it was around the same depth as the previous check your gas level make sure theres enough for the pump to be emerged under if you then get pressure its most likelely the little rubber hose is letting the pressure out of where it clamps on your sender if not check your fuel pressure regulator faulty internal diaghram rupture good luck please rate

It should not cause no problems but instead of removing the tank leave it in the truck take out all the fuel in the tank and jus discontinue use of it. This will save you alot of time and trouble and i also suggest that if anyone besides you drives this vehicle then i would put a locking gas cap on it so it cant be accessed at anytime except by you.

I would say that physically the transmission may fit due to the engine sizes being the same, but the 96 F150 is a E4OD transmission and the 01 is a 4R70W transmission, they do not work the same electrically.

check to see if you have a flapper valve that operates your feul injection if you do you might have to replace it.
