BMW N55 F-Chassis Spool Stage 2 Low Pressure Fuel Pump

The Spool Stage 2 low pressure fuel pump for N55-powered F-chassis BMWs is a complete drop-in replacement that flows about 30% more than the factory pump.

Why you need it

Once upgraded high pressure pumps can supply more direct injection fuel, the factory low pressure pump becomes the bottleneck, especially on E85. This Stage 2 pump supports almost 600 hp of low pressure fueling on any fuel type.

Good to know

Do not overload the primary pump: very high fuel pump demand set in the tune can melt the primary pump connector. A matching tune is needed to use the extra flow.
