Description : Primary fuel pump ULPK0041 is a new digitally designed brushless pump used to lift the fuel from the tank into the engine fuel system. Designed to ensure the correct level of pressure and flow into the fuel system, correct flow rate and pressure are critical to prevent the issues of vaporization and cavitation can lead to implosion and damage to surfaces. Perkins fuel pumps are carefully selected during our engine design to provide the flow and pressure required for the whole fuel system and tested for many thousands of running hours to ensure maximum performance and smooth running and power. Uses high-performance seals to ensure long life and deliver correct pressure whatever the conditions. ULPK0041 is supplied with a wiring harness to fit older pre-2013 engines. A cost-effective alternative lift pump ULPK0038A is also available for all out of production warranty engines. This pump is an older technology designed pump which includes brushes and stator. This pump can be used on both pre 2013 engines originally fitted with the lift pump 4132A018 and also to replace the post 2013 engines original lift pump T414444 (sold in kit ULPK0041) when out of warranty. The pumps can be distinguished by the electrical connection points, in ULPK0041 the electrical connection points down towards the filter bowl and with ULPK0038A the electrical connection points horizontally outwards.
