I successfully changed the fuel pump on my 2001 Ford Ranger 3.0L 126" wheelbase, flex-fuel truck [1]. But I have some unanswered questions, and they'll plague me the rest of my life if they remain so.
Is there a fuel pump timer? How does it work, and where is it?
If indeed, the pump is cooled by fuel going *through* the pump, what's the advantage of placing the pump *in* the tank?
How come Ford has different pumps for different wheelbase trucks that are the same otherwise? How can the wheelbase, differing by a few inches, have anything to do with the pump?
[1] The "flex-fuel", meaning can take either methanol+gasoline mix or straight gas, part is indicated by the 8th character of the VIN, V for flex-fuel, U for only straight gas. Apparently that detail is needed to get the correct pump.-- (||) Nehmo (||)
