What this part does
The fuel pump module assembly sits inside the gas tank and delivers pressurized fuel to the engine's high-pressure injection system. It maintains the specific volume and baseline pressure required for the BMW V8 engine to operate correctly across all load conditions. This complete unit also houses the fuel level sensor that transmits tank volume data to the instrument cluster and body domain controller. A failing unit typically causes extended cranking, hesitation under acceleration, lean fault codes, or a complete engine stall and no-start condition.

Before you order
Compare the electrical connector on your original unit against the provided images, as pin configurations can vary based on auxiliary heating and specific trim options. The system must be depressurized before removal, and it is highly recommended to use a new rubber lock ring seal during installation to prevent EVAP system leaks and cabin fuel odors. Clear any stored fuel pressure fault codes in the engine control module after installation.
