Primary fuel pump 2641A203 to move the fuel from the tank into the engine fuel system. Designed to ensure the correct level of flow and pressure into the fuel system, correct flow rate and pressure are critical to prevent the issues of cavitation and vaporization that can lead to implosion and damage to surfaces. Perkins fuel pumps are carefully selected during our engine design to provide the pressure and flow required for the whole fuel system and tested for many thousands of running hours to ensure smooth running and maximum performance and power. Uses high-performance seals to ensure long life, and deliver correct pressure whatever the conditions.
