Precision Raceworks High Performance Fuel Pump - BMW F-Series S55

Precision Raceworks' F-Series S55 High Performance Fuel Pump is a drop-in replacement for the factory in-tank pump assembly, built for owners running E85 or other high-volume fuel blends. Each stage ships fully assembled and ready to install, with no core charge.

The design keeps the primary pump fully submerged regardless of fuel level or the g-forces of hard driving, and every stage installs without cutting or splicing the factory wiring.

Frequently Asked Questions

Do I need to cut my wiring harness to install this?No. Every stage is a drop-in, plug-and-play installation.

Which stage do I need?It depends on your target power and fuel. Stage 3 and Stage 3 Brushless support up to 900whp on pump gas; Stage 4 and Stage 4.5 support 1,000whp or more. Contact your BMP Tuning rep or your tuner to confirm the right stage for your build.

Is there a core charge?No. Each stage ships fully assembled with no core charge.

What's the difference between Stage 3 and Stage 3 Brushless?Stage 3 pairs the OEM brushless pump with an added external Walbro pump. Stage 3 Brushless instead replaces the OEM pump with a single upgraded brushless unit, so it looks nearly identical to the factory setup.
