Fuel Tank Assist Pump for Mitsubishi SUVs

This auxiliary fuel pump keeps a steady fuel supply from the tank to the engine, especially on long trips, steep climbs, or off‑road. It supports the main in‑tank system, stabilizes flow, and helps quick cold starts. Built to OE standards, it fits the factory housing and connectors for a clean, plug‑and‑play repair.

Why you need it

Without a healthy assist pump, the engine can run lean under load, hesitate in corners, or stall when fuel sloshes. It protects the primary pump by sharing the work, improving reliability and longevity.

How it works ⚙️

An electric turbine draws fuel through a fine strainer, equalizes tank sections, and feeds stable pressure to the rail. A check valve holds line prime after shutdown. The ECU/relay powers it for a short prime at key‑on and continuous running when the engine is on.

What happens if it’s broken

Hard starts, long cranking, loss of power at high RPM, surging on hills, sputter with low fuel, lean codes, misfire, or pump whining. Prolonged failure can overheat the main pump and damage the catalytic converter.

Pro tips

Listen for a 2–3 s hum at key‑on, verify pressure and flow, check grounds and connectors, replace strainer and tank seal, and handle fuel safely. Use parts rated for E10/E15.
