The 28591964 is a Delphi‑compatible high‑pressure common rail diesel pump engineered for precise fuel delivery, stable rail pressure, and long service life in modern diesel engines. As a direct replacement for original Delphi pumps, it is widely used in Ford, Citroën, Peugeot, Fiat, and selected Land Rover commercial vehicles. It provides reliable cold‑start performance, smooth power delivery, and reduced emissions.
Structural Features & Compatibility
Delphi OEM‑compatible interface – Mounting flange, drive coupling, fuel inlet/outlet ports, and electrical connections match original Delphi specifications for straightforward installation.
Radial multi‑piston design – Delivers smooth, pulsation‑free high‑pressure fuel to the common rail, maintaining consistent pressure under all engine loads.
Hardened internal components – Precision‑ground plungers, cam ring, and bearings reduce wear and maintain output even after high mileage.
Corrosion‑resistant housing – Treated aluminium alloy body protects against moisture, road salt, and diesel contaminants.
Integrated control compatibility – Works with the original inlet metering valve (IMV) and pressure control valve, allowing the ECU to manage rail pressure accurately.
100% flow‑tested – Each pump is calibrated and tested to meet or exceed OEM performance standards, ensuring seamless integration with the engine management system.
