Something is going wrong with my feul system. I put it on the front tank and it works a little then it acts like I am getting no feul. I switch to the back tank and it works better. The back tank is getting worse. Could this be the switch or what.

sounds like fuel devertor valve is not switching. it is pumping feul from front tank to rear. try letting front tank go dry and use back tank only..

if the fuel lines have any rubber fuel lines they could be sucking air. also try replacing the fuel caps, it may not be venting

Sounds like vapor lock. Leave the cap from the gas lid undone for a little while.

you have to put the back tires on ramps thin put something in front of the front tires so it dont roll of the ramps .thin you put jacks under the feul tank to hold it up...thin you go under it an take the feul straps off thin drop the tank an the take the feul pump out an put the new one in

did you change feul filter? some of these will install backwards and will have no flow.is there enough feul in tank? did you replace or clean sock at bottom of feul pump

start checking fuel pressure easier then changing pump re check that all is plugged in by air cleaner

Depending on how much gas you put in it,
The fuel pump and gas gauge are all in one unit.The fuel pump uses the gas in the tank to keep it lubricated,So when you run out,It's like running an engine with no oil.
A little trick that will get you one more start to get you to a shop to replace the pump is to,
take a rubber hammer or something and hit the bottom of the gas tank about four times to loosen the fuel pump from it's binding bearings.

could be low pressure or the evap/emissions. could tell more with a pcm code.

You need to replace the fuel tank switch. This is a common problem with the Fords. The switch is about $40.00.

Nope.. It's probably your pump mounted injection module (or injection pump) what ever you wanna call it.. A little control box up in the engine compartment next to the intake.. little 4 wire connection.. Pain in the **** expensive..
