The Precision Raceworks BMW F3x & F2x B58 High Performance Fuel Pump are designed for customers looking to run all blends of E85. These drop-in pumps include a Walbro fuel pump capable of flowing up to 300% more fuel than the factory fuel pump and are 100% E85 compliant.

By design, a fuel pump such as this is ideal for daily driving and racing applications of all kinds. This system keeps the primary pump fully submerged in fuel regardless of tank level or the g-force the car is subjected to.
