Precision Raceworks E9X / E8X Bucketed Low Pressure Pump Upgrade (Non-Modular) – BMW N54 / N55

OVERVIEW

The Precision Raceworks non-modular bucketed upgrade is a fully assembled, drop-in replacement for the factory in-tank low-pressure pump on E8X and E9X N54 and N55 cars. It installs like the OEM pump and flows up to 350% more fuel.

It keeps the factory-style bucket, so the pickup stays covered at low fuel level, but it is built for one power target and cannot be expanded later. Choose it if Stage 2 or 2.5v2 is where the car will stay; if you may want more fuel later, choose the modular bucketed pump instead.

TECH RESOURCES

Required Extras

• Precision Raceworks E9X / E8X In-Tank Fuel Filter & Regulator V2 (601-0244) — required to reach the advertised flow and horsepower ratings.
