Product Description
This low-pressure fuel pump (LPFP) assembly increases fuel volume to support high-horsepower BMW N54 applications and ethanol-based fuel blends. The kit replaces the factory fuel bucket with a brand new core equipped with a high-output Walbro 450 pump. Designed for seamless installation in E-chassis 135i, 335i, and X1 35i models, no wiring changes are required. Direct replacement for BMW OEM part #16147163298.
Key Features:
- E85-compatible Walbro 450 pump (F90000274)
- Ships fully assembled and ready to install
- Complete replacement fuel bucket with top hat and float assembly
- Includes Walbro filter, fittings, and O-ring
- Plug-and-play installation, no wiring modifications
- Supports up to 575 WHP on pump gas (500 WHP on full E85)
EKP Compatibility Notice: Upgraded pumps draw more current than stock, so if you're on a weak or aged EKP2, it may overheat and shut down. We recommend upgrading to an EKP3.
Note: For European spec vehicles, the original top hat may need to be transferred over during installation.
