Spool Performance Stage 3 In-Tank Twin Pump Fuel Supply for BMW N55

Ready to push your N55 further on petrol or ethanol blends. This Stage 3 in-tank dual pump assembly from Spool Performance gives your BMW the fuel headroom serious builds demand. The auxiliary pump activates with boost to keep the low side pressure rock solid under load, delivering almost twice the flow of the factory unit and supporting over 1200 whp worth of low side fuelling capacity, whatever fuel you run.

We have fitted this kit on customer cars and our own development vehicles with outstanding results. Throttle response stays crisp, drivability remains OEM-like, and fuel supply remains stable on high boost and E blends. If you are stepping up to a hybrid or larger turbo and want reliable fuelling on the N55, this is the go to solution.
