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.
