Parts for your 1988 Mitsubishi Pajero-Fuel pump

1988 Mitsubishi Pajero fuel pump — what it does and when to service it

Based on technical sources like the 1988 Mitsubishi Pajero Factory Service Manual, the Haynes Mitsubishi Pajero/Montero 1983–1996 manual, and the Mitsubishi ASA/EPC parts catalogue, a fuel pump is relevant and used on the 1988 Pajero. Every engine option fitted that year relies on a pump to move fuel from the tank to the engine, but the style differs by engine.

• 2.6L 4G54 petrol (carburetted): mechanical, cam-driven pump on the engine.
• 3.0L V6 6G72 petrol (EFI): electric, in-tank high-pressure pump.
• 2.3/2.5L diesel (4D55/4D56): rotary injection pump with an integrated mechanical feed function and a hand primer at the filter (no factory in-tank electric pump).

On a 1988 Pajero, the fuel pump’s job is straightforward: deliver the right volume of fuel at the right pressure so the donk runs cleanly whether you’re towing, touring, or tackling a rutted track. Carb petrol models only need low pressure, so the simple mechanical pump does the trick. EFI V6 models demand steady high pressure
