Spool - Stage 3 Low Pressure Fuel Pump DIY Kit || F90

Spool Performance is thrilled to bring our BMW S63 Stage 3 Low-Pressure Fuel Pump kit to market for enthusiasts who are up for a DIY solution to their fueling issues. With the use of high-pressure pumps now being able to support DI fueling, we have found the low-pressure electric fuel pumps that deliver fuel from the tank to the high-pressure pumps to be a bottleneck while chasing high horsepower, especially on E85 fuel. 

The DIY Kit brings a similar flow as plug-and-play kits but at a fraction of the cost.  The kit includes everything needed to add a secondary boost-activated low-pressure pump to solve any low-side fueling capacity issues. This provides almost double the flow from a stock pump and should be more than enough for over 1200whp worth of low-pressure fueling regardless of fuel type.

The kit is easy to assemble with provided instructions and includes :

1x Dual Pump Bucket Assembly 

1x Secondary Fuel Pump Activation Harness

1x Boost-activated Switch 

1x Boost reference adapter

1x Hardware pack
