Bosch New Fuel Injection CP3 Pump 0 445 020 377 for 2022–2024 Ram 6.7L Cummins
The Bosch 0445020377 high-pressure fuel injection pump is a direct-replacement common rail pump engineered for 2022–2024 Ram 2500/3500 trucks equipped with the 6.7L Cummins diesel engine. Built by Bosch, the original equipment manufacturer for many modern diesel fuel systems, this pump is designed to restore factory fuel pressure, precise fuel metering, and dependable engine performance when replacing a worn, contaminated, or failed unit. For late-model Ram Cummins applications, proper rail pressure and fuel delivery are critical for emissions control, throttle response, towing performance, and cold-start consistency.
This new OEM-spec pump is manufactured to exact tolerances for compatibility with the factory fuel system, injectors, rail sensors, and engine calibration. It is an ideal solution for trucks experiencing hard starts, low rail pressure codes, drivability issues, or fuel pump wear. Whether servicing a stock work truck or maintaining a heavy-duty towing application, replacing the high-pressure injection pump with a genuine Bosch unit helps restore reliability and maintain long-term engine health.
