Mercedes Sprinter High-Pressure Fuel Pump – Bosch | VS30 2.0L OM654 Diesel | #654070440164 (2022–2025)

A failing high-pressure fuel pump on a VS30 Sprinter starves the common-rail system of the pressure it needs to fire the injectors correctly — causing hard starts, power loss, rough running, and fault codes that won't resolve until the pump is replaced. This is the Bosch high-pressure fuel pump for VS30 Sprinters equipped with the 2.0L OM654 diesel engine, a direct replacement that restores the rail pressure, injection timing, and fuel delivery precision the OM654 common-rail system depends on.

What This Part Does

The high-pressure fuel pump is the heart of the common-rail injection system. It takes low-pressure fuel from the lift pump and compresses it to the extreme pressures — up to 2,000 bar on the OM654 — required for direct injection. That pressurized fuel is stored in the fuel rail and distributed on-demand to each injector, which the ECU fires in multiple precisely timed events per combustion cycle. This multi-event injection strategy is what gives the OM654 its efficient combustion, low noise, and strong low-end torque. When the pump wears, loses efficiency, or fails outright, rail pressure drops below spec and the entire injection strategy collapses — affecting power, fuel economy, and emissions simultaneously.

Common Symptoms of a Failing High-Pressure Fuel Pump

• Hard starting, especially when cold or after sitting overnight
• Loss of power under load, particularly at highway speeds or when accelerating
• Rough or unstable idle, misfires, or uneven engine running
• Check engine light with fault codes related to fuel rail pressure or fuel metering
• Engine entering limp mode due to insufficient rail pressure
• Excessive black smoke under acceleration

When to Replace

Replace when rail pressure fault codes are confirmed and the pump is diagnosed as the source after ruling out the fuel pressure regulator, metering valve, low-pressure supply, and fuel filter condition. Also replace during a full fuel system overhaul when injectors are being replaced — contamination from a failing pump can damage new injectors if the pump is left in service.

VS30 OM654 Specific — VIN Verification Required

This pump is for VS30 Sprinters equipped with the 2.0L OM654 diesel engine. It is not compatible with VS30 models equipped with the 3.0L OM642 or NCV3 Sprinters equipped with the 2.1L OM651. Always verify your engine code and VIN before ordering. Contact us and we'll confirm fitment before you buy.
