Fuel Injection Pump
The Fuel Injection Pump, with part number 3964556, is an essential component of a truck's fuel system. It is responsible for pressurizing and delivering fuel to the engine's combustion chambers at the correct time and in the correct amount. This pump is typically driven by the engine's camshaft and uses a series of mechanical components to create high-pressure fuel that is then delivered to each individual injector. The Fuel Injection Pump must be properly calibrated and maintained in order to ensure optimal engine performance and fuel efficiency.
