Detailed Product Information

Bosch 66848 is built for gasoline fuel injection systems that rely on a high pressure pump to supply the engine with the fuel pressure needed for direct injection operation. The pump uses a single electrical connector, blade terminals, and a bolt-on mounting style. Its steel and metal construction supports long-term service in demanding underhood conditions, while the included fuel filter and O-ring/seal components help support a proper fuel system service replacement.

This part cross-references BMW 13518631642 for the same application. It is a fitment-based replacement for BMW 230i, BMW 430i, BMW 840i, BMW M2, BMW M3, BMW X3, BMW Z4, and MINI Cooper applications listed below. Bosch 66848 is also relevant for drivers searching for a BMW GDI high pressure fuel pump replacement or a MINI Cooper direct injection fuel pump.

What This Pump Helps Address

• Hard starting caused by insufficient high-pressure fuel delivery
• Fuel pressure loss in direct injection systems
• Rough idle related to inconsistent pump output
• Acceleration hesitation tied to fuel starvation at the rail
• Check engine light conditions associated with fuel pressure faults

Before installation, confirm the vehicle’s fuel system configuration, connector style, inlet and outlet dimensions, and OE part number match the original pump. Because this is a direct injection high pressure fuel pump, clean fuel system practices and correct torque procedures are important during service.
