Can anyone tell me how to change a fuel filter and/or pump on a 94 Jeep Grand Cherokee Laredo?

I have a 94 Jeep Grand Cherokee Laredo that sputters when I step on the gas. It stalled this morning when I was idling at a stop light but started right back up again. Could this be the fuel filter or fuel pump? Is the fuel filter located in the gas tank? If anyone can give me a walk-through on how to change the fuel filter and/or pump, I would greatly appreciate it.

The fuel pump is located inside the fuel tank. To change the fuel pump you will have to remove the fuel tank.



There is an inline fuel filter that is not so hard to change. Try that first. It is located near the fuel tank under the rear of the Jeep.



Stalling at idle is more likely caused by a dirty idle speed control solenoid. This can be cleaned by spraying throttle body cleaner into the little slot near the throttle plate inside the throttle body.



Before servicing the fuel pump or filter, you need to test the fuel pressure. Many auto parts stores have loaner tools available or they may check it for you. The tool consists of a pressure gage that connects to the fuel pressure test port. Normal pressure for the aniline six is around 40psi. A faulty fuel pressure regulator can cause the problems you are seeing as well.



If you do remove the fuel pump form the tank, pay close attention to he rubber hose that connects the pump to the lines. I just had a time tracking down a mystery fuel pressure problem in a Cherokee that turned out to be a pin hole in that little rubber hose.
