Fuelpumpreplacementguide. - 1992 Chevrolet Lumina

The fuel pump is located inside the fuel tank. You will have to pull the tank, so get out any esscess fuel you can. Undo the battery, red cable first, Jack up the rear of the car and support it on jack stands high enough to pull the tank down and out the rear. Disconect any rubber hangers at the rear of the exhaust so the pipe will rest on the rear axel. Disconect the filler hoses from the tank. Disconect the fuel lines, you may have to have a special tool to dosconect the fuel lines, ck at your local parts store for any you may need. Support the taqnk with a floor jack and remove the retaining bolts/straps. Lower the tank and disconect any wiring from the sending/pump location. Pull the tank down and out the rear. The fuel pump is held in with a loc-ring, you can use a screw driver to turn half way to remove, then the assy. will come out. 

To replace the fuel pump the fuel tank must be removed, this requires the car be jacked off the ground as far as poss and put on safety stands (always use safety stands!!), the filler neck is then disconnected and then the steel straps tha retain the tank into the car are undone (each has a nut), then the tank is lowered on a jack until u can get to the electrical connectors and the fuel lines and vapor lines, a special tool may be required to remove the fuel pressure and return line, trhe pump assembly is held into the tank by a twist out retainer ring, reverse to install pump and tank back into the car, this is a 2 person job on the ground, be careful, even a small spark from a tool and u are toast.
