The Precision Raceworks BMW G8x M2/M3/M4 S58 Hybrid Primary Fuel Pump (Stage 2-2.5) Kits are designed for customers looking to run all blends of E85. These pumps are ideal for those wanting to run a single fuel line to the front of the car, efficiently feeding both the high-pressure fuel pump and port injection from a single pump assembly.

Caution!

Many other companies selling pumps do not protect your high-pressure fuel pump or direct injectors with their fuel pump options. When comparing other brand pumps to Precision Raceworks, ensure there is a fuel filter in the system after all electric pumps, whether in the tank or in the fuel line. Brands using a Y-fitting to join the factory pump (after the factory filter) and an additional pump without including an inline fuel filter are cutting corners, leading to premature failure of the high-pressure fuel pump and direct injectors.
