S55 fuel pump buying guide
Compare BMW S55 fuel pump upgrades for both sides of the fuel system. Colorado N5X offers Precision Raceworks low-pressure fuel pump options and a Nostrum twin high-pressure pump kit. Choose the component that matches your fueling plan.
S55 low-pressure fuel pump upgrades
The Precision Raceworks F-Series S55 fuel pump upgrades the tank-side low-pressure supply. Review the available stages, E85 specifications, pump activation requirements and included components. The selected stage determines the pump arrangement and supporting hardware; check its details before ordering.
S55 high-pressure fuel pumps
The Nostrum S55 twin standard-bore high-pressure pump kit addresses the direct-injection side. A high-pressure pump kit and a low-pressure pump upgrade are different components, with different installation and tuning requirements. Review the manufacturer's specifications for the fuel blend and calibration you plan to use.
Plan the complete fueling setup
Discuss the target fuel blend, current hardware and required capacity with your tuner. An upgraded pump alone does not add port injection. If supplemental injection is part of your plan, compare the BMP S55 port injection kit and the appropriate controller and wiring.
