How to Replace a Fuel Pump in a Jeep Grand Cherokee

138

The Jeep Grand Cherokee has an electric fuel pump so you should ensure that its fuses and relays are working before checking it. You may need to clean your fuel pump or replace it if your gas tank is not empty, but your vehicle has difficulty getting fuel. The Jeep Grand Cherokee comes in a variety of styles and trim levels that can affect the replacement fuel pump you choose.

Step 1

Determine which fuel pump your Jeep Grand Cherokee will need. This depends not only on the make and model, but also the engine size. Models made from 1999 to 2004 may be equipped with a 2.7 L OM647, 3.1 L 531, 4.0 L PowerTech, or 4.7 L PowerTech engine. Models made after 2004 can have a 3.0 L OM642, 3.7 L PowerTech, 4.7 L PowerTech, 5.7 L Hemi or 6.1 L Hemi.

Step 2

Position your vehicle over a hoist and relieve the fuel system pressure. Raise your vehicle and drain the tank by loosening the clamp and removing the fill hose.
