How to Replace a Fuel Pump in a Mitsubishi Eclipse

by Editorial Team

The Mitsubishi Eclipse has an electric fuel pump so you should check its fuses and relays and ensure you have fuel before performing the more difficult task of inspecting the fuel pump. If your vehicle still has difficulty getting fuel you may need to clean or replace the fuel pump. The Mitsubishi Eclipse's variety of styles can affect the replacement fuel pump you choose.

Step 1

Determine which fuel pump your Mitsubishi Eclipse will need. This depends not only on the make and model, but also the engine size. Models of the Mitsubishi Eclipse made from 1995 to 1999 offer choices of 2.0 L or 2.4 L engines and models built from 2000 to 2005 can have a 2.4 L or 3.0 L engine. Models manufactured after 2005 can be equipped with a 2.4 L or 3.8 L engine.

Step 2

Prepare your vehicle for fuel pump servicing. Relieve the fuel system pressure and disconnect the negative battery cable with a wrench. Take out the rear seat cushion by pulling the seat stopper out and lifting the lower cushion up. You can now remove the inspection cover on the passenger side of the vehicle.

Step 3

Disconnect the fuel lines and unplug the fuel pump's electrical harness. Remove the locking ring on the fuel pump assembly with a wrench if your vehicle has all wheel drive. Remove the fuel pump from the fuel tank.

Step 4

Install the new fuel pump into the fuel tank using the items included in the kit. Tighten the locking ring over the fuel pump if your vehicle has all wheel drive.
