Spool Performance is thrilled to bring our BMW S63 Stage 3 Low-Pressure Fuel Pump kit to market.? The kit includes everything needed to add a secondary boost-activated low-pressure pump to solve any low-side fueling capacity 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 upgraded stage 3 low-pressure pump kits are a solution for that and it features a twin pump solution with one pump coming in during boost onset. 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.
?This kit includes :
1x Dual Pump Bucket Assembly?
1x Secondary Fuel Pump Activation Harness
1x Boost-activated Switch?
1x Boost reference adapter
1x Hardware pack
