Parts for your 2025 Mitsubishi Eclipse cross-Fuel pump

Fuel pump for the 2025 Mitsubishi Eclipse Cross

Yes, a fuel pump is absolutely relevant and used on the 2025 Mitsubishi Eclipse Cross. Technical sources including the Mitsubishi Motors 2025 Eclipse Cross Owner’s Manual (AU/NZ), the factory Service Manual (Fuel/Engine Control sections), and the Mitsubishi parts catalogue all list an electric in-tank fuel pump module. For the 1.5L direct‑injection turbo (DI‑T) petrol models, these sources also identify an engine‑mounted high‑pressure fuel pump (HPFP) that feeds the common fuel rail. The Eclipse Cross Plug‑in Hybrid EV (PHEV) is likewise petrol‑fuelled and uses an in‑tank pump to supply the engine’s fuel system.

On this model, the in‑tank electric pump lifts fuel from the tank and maintains steady low‑pressure supply to the engine. In the 1.5L DI‑T variants, that supply is then stepped up by a mechanical HPFP to the very high pressures needed for direct injection. In the PHEV, the in‑tank pump supports the petrol engine when it’s called in to assist the drive battery. Either way, the pump’s job is to keep the engine fed clean, cool fuel at the right pressure so it starts crisply, idles smoothly and pulls strongly.

There’s no scheduled fuel‑pump replacement interval on a 2025 Eclipse Cross. The pump and its in‑tank filter (strainer) are designed to last the life of the vehicle under normal use. Good habits help: refuel at reputable servos, avoid frequently running below a quarter tank to keep the pump submerged and cooled, and follow the fuel grade recommended in the owner’s manual. If the engine cranks longer than normal, stumbles under load, surges at highway speeds, or logs fuel‑pressure faults, it’s time for diagnosis.

For servicing, a technician will typically check live fuel‑pressure data, listen for pump priming, verify pump relay/fuse operation, and inspect connectors and earths. On DI‑T models they’ll also confirm HPFP performance and look for rail‑pressure deviations. If the in‑tank module needs replacement, it’s accessed via the rear seat service cover, the locking ring and seal should be renewed and refit to spec. Use a quality OE or equivalent module to maintain correct pressure and flow. For PHEV variants, the workshop follows the high‑voltage power‑down procedure before any fuel‑system work.

• Common symptoms of a tired pump: hard starting, hesitation on hills, noisy whine from the tank, lean/misfire fault codes.
• Care tips: keep at least a quarter tank, don’t ignore early symptoms, and address contaminated fuel quickly.

FAQs

Does the 2025 Eclipse Cross have one or two fuel pumps?
The 1.5L DI‑T models use two: an electric in‑tank lift pump and a mechanical high‑pressure fuel pump on the engine. The Eclipse Cross PHEV uses an electric in‑tank pump to feed its petrol engine’s fuel system, without a separate HPFP for direct injection.

When should the fuel pump be replaced?
There’s no time‑based replacement. It’s replaced when testing confirms low flow or pressure, noisy operation, or fault codes pointing to pump performance. Because the filter is integrated with the module, the whole in‑tank assembly is typically renewed.

Is it okay to keep driving with a weak fuel pump?
Not a great idea. A weak pump can cause lean running, misfires, poor performance and potential catalyst damage. Get it checked early to avoid being stranded and to protect the engine and emissions system.
