Parts for your 2016 Mitsubishi Asx-Fuel pump

2016 Mitsubishi ASX fuel pump — what it does and when to service it

Yes, a fuel pump is absolutely fitted to the 2016 Mitsubishi ASX. Technical references confirm it: the Mitsubishi Motors Service Manual for ASX/RVR/Outlander Sport (2016, Group 13A – Fuel and Engine Control) specifies an in-tank electric fuel pump module for petrol variants, while diesel models use a low-pressure lift pump and an engine-mounted high-pressure pump for the common-rail system. The Mitsubishi ASA electronic parts catalogue also lists the in-tank fuel pump module for petrol ASX models and the relevant supply/high-pressure pumps for diesel trims.

On the 2.0L petrol ASX, the in-tank electric pump sends fuel forward at a steady pressure so the injectors can do their job cleanly. The module typically bundles the pump, strainer, pressure regulation components, and the fuel level sender. Diesel ASX models add a high-pressure pump on the engine to reach common-rail pressures. Either way, the pump’s purpose is simple: reliable fuel delivery across hot summers, cold starts, long commutes, and open-road touring across Australia and New Zealand.

For servicing, the fuel pump on petrol ASX models isn’t a routine replacement item. It’s designed to last the life of the vehicle if fed clean fuel. Good habits help: keep at least a quarter of a tank to keep the pump submerged and cool, buy quality fuel, and replace the diesel fuel filter on schedule (diesel only). If performance drops off, the engine hesitates, there’s a loud whining from the tank, or it cranks longer than normal, a fuel pressure test and scan (codes like P0087/P0089) will quickly point a technician in the right direction.

Replacement is straightforward for a trained tech. The petrol pump module is accessed under the rear seat through a service cover. The old lock ring and seal are removed, the module is swapped, and new seals/lock ring are fitted. It’s critical to depressurise the system, disconnect the battery, ventilate the work area, and avoid sparks. Diesel models may need priming after filter or pump work. Fresh seals, correct torque on the lock ring, and verifying fuel pressure/rail data on a scan tool are part of a tidy job.

• Typical signs of trouble: hard starting, stalling, surging under load, noisy pump, poor economy.
• Practical tips: don’t run it dry, stick to reputable fuel, and service the diesel filter on time.

FAQs

Does a 2016 Mitsubishi ASX actually have a fuel pump?
Yes. Petrol versions use an in-tank electric fuel pump module, while diesel versions use a lift pump and a high-pressure pump. This layout is documented in the Mitsubishi Service Manual (Group 13A) and the Mitsubishi ASA parts catalogue.

How long should the fuel pump last on a 2016 ASX?
With clean fuel and sensible driving, many last well beyond 150,000–250,000 km. It isn’t a scheduled replacement item on petrol models. Consistent hot-weather running with low fuel levels or contamination can shorten its life.

What does replacing the fuel pump involve on the petrol ASX?
A technician accesses the pump under the rear seat, removes the lock ring and seal, swaps the module, fits new seals, and verifies pressure. Safety steps include battery disconnection and fuel system depressurising. Diesel systems may require priming after work.
