335D Lift Pump Upgrade

This is a lift pump upgrade kit for all 335D E90 M57's running dual CP3 pumps! All parts are 100% brand new and custom assembled by Precision Raceworks for WPI! The factory bucket design is retained making this kit a direct replacement for the OEM unit, but with a Walbro 535 fuel pump. Your top hat must be transferred over to the new bucket assembly.

The 535 draws 18.X amps per test bench measurements. The OEM BMW EKP is rated and fused for 20 amps. Some cars have thrown an overcurrent fault in the EKP but it does not set a check engine light. Our personal test car has logged over 25k miles with the OEM EKP and the Walbro 535 with no issues. 

Those looking for an upgraded EKP solution, these are the two options we know of https://speedsty.com/products/ekpm-replacement-board?variant=44445909909814 and https://www.eospeed.com/products/bpm4-low-pressure-fuel-pump-controller .
