Parts for your 2013 Mitsubishi Outlander-Fuel pump

2013 Mitsubishi Outlander fuel pump — what it does and how to look after it

Based on technical references such as the Mitsubishi Outlander (GF/GG) Workshop Manual (Engine Fuel—MFI and Diesel Common Rail sections), the Electrical Wiring Diagram for the 2013 model range, and the Mitsubishi ASA electronic parts catalogue, the 2013 Mitsubishi Outlander is fitted with a fuel pump. Product Safety Australia recall bulletins issued for certain 2013–2019 Outlander vehicles referencing in-tank fuel pump modules further confirm its use. So yes—whether petrol, diesel, or PHEV, this model relies on a fuel pump.

On this Outlander, the in-tank electric fuel pump draws petrol or diesel from the tank and delivers it to the engine at the pressure the system expects. Petrol variants use the in-tank pump to supply steady pressure to the fuel rail for multi-point injection, while diesel models pair an in-tank lift pump (or supply arrangement) with a high-pressure common-rail pump on the engine. Either way, without a healthy pump the engine can be hard to start, stumble, or lack power under load.

As part of regular servicing, a fuel system pressure check is a smart move. For petrol Outlanders, the filter is typically integrated into the pump module and not a separate service item, when it clogs or the pump wears, the whole module is usually replaced. Diesel Outlanders do have a serviceable under-bonnet fuel filter—changing it on schedule helps protect the high-pressure pump and injectors. Keeping at least a quarter-tank of fuel on board helps cool and lubricate the in-tank pump, especially in hot Aussie and Kiwi summers.

Replacement is straightforward for a trained tech: disconnect the battery, safely relieve fuel pressure, lift the rear seat base and access the pump through the service cover, then remove the lock ring and swap the module with a new seal (O-ring). The lock ring should be refitted to spec and the system checked for leaks. Diesel systems demand extra cleanliness and proper priming to avoid introducing air, some require scan-tool routines or manual priming after filter or component replacement.

• Common signs of a crook pump: long cranking, whining from the tank, hesitation on hills, sudden stalling, or fault codes like low fuel pressure (e.g., P0087).
• Best practice: use quality fuel, replace the diesel filter per the logbook, and inspect/pressure-test the petrol system during routine servicing.

Does a 2013 Mitsubishi Outlander have a fuel pump?

Yes. Technical documentation for the GF/GG series shows an in-tank electric fuel pump module for petrol models, and diesel variants use a supply arrangement plus a high‑pressure pump on the engine. Wiring diagrams also show a fuel pump relay and related controls.

Where is the fuel pump located?

It’s housed in the fuel tank as a single module that includes the pump, strainer, and level sender. Access is typically under the rear seat via an inspection cover, which means the tank often doesn’t need to be dropped for replacement.

How long should it last, and when should it be replaced?

Many last well past 150,000 km, but heat, low fuel levels, and contamination can shorten life. Replace it if pressure tests fail, the pump is noisy, starting becomes difficult, or diagnostics point to fuel delivery issues. Diesel owners should keep the fuel filter changes up to date to extend system life.
