I have a 1992 Chevy S10 pick up and the fuel pump on my truck is inside the gas tank.
It is hidden behind the frame rail just under the driver side door. It is about the size of a soup can.
It is inside of the fuel tank.
We've changed the fuel pump, pressure regulator, gas cap, and had a tune up and the pressure is still building...What else can it be?
