What this part does
The high-pressure fuel pump is a critical mechanical component in the direct injection system. It takes standard low-pressure fuel delivered by the electric pump in the gas tank and compresses it to extreme pressures, often exceeding 2,000 PSI, before delivering it to the fuel rail and injectors. On the 4.4L V8 engine, there are two of these pumps; this specific unit is mounted on the right (passenger) cylinder head and is driven mechanically by a dedicated lobe on the camshaft.
Because the pump relies on precise internal tolerances to build pressure, mechanical wear or failure of the integrated electronic quantity control valve will disrupt fuel delivery. When this occurs, the engine control module detects the pressure drop and triggers a limp-mode state to protect the engine. Common symptoms of a failing high-pressure pump include extended cranking times, rough idling, random cylinder misfires, poor acceleration, and a prominent drivetrain malfunction warning on the dash display.

Before you order
- Verify which side of the engine requires replacement. This pump fits the right (passenger) side cylinder bank. The left side utilizes a different pump configuration and they are not interchangeable.
- Match your current pump's Bosch or BMW part number to the numbers listed above to guarantee proper fitment and electronic compatibility.
- BMW factory procedures require the replacement of the high-pressure fuel line connecting the pump to the rail, as the fittings crush to seal and are strictly single-use.
- Inspect the roller tappet (cam follower) that rides between the camshaft and this pump. If it shows scoring, pitting, or uneven wear, it must be replaced to prevent immediate damage to the new pump.
