Stage 2 High-Flow In‑Tank Fuel Pump Module for BMW N54 and N55 E Chassis

Unlock reliable fuelling for tuned twin‑turbo BMW builds with this complete in‑tank pump module. Designed for E8x and E9x platforms running the N54 or N55 3.0 turbo engine, this drop‑in assembly replaces the factory bucket and delivers roughly double the flow of the stock unit. Ethanol compatible and built around the proven Walbro 450 pump, part number F90000267, it keeps fuel rail pressure stable on hard acceleration and high load, whether you run petrol, race fuel or E blends.

Ideal for BMW 1 Series M Coupe, 135i and 335i owners building fast road or track cars, this Stage 2 solution supports up to around 600 whp on petrol or race fuel and up to around 550 whp on E85. Every unit is flow tested before dispatch for consistent performance you can trust.
