Description

The Fuel Injection Pump, also known as the fuel pump, is a crucial component of a truck’s engine system. Part Number 3973198 3976438 3977571 specifically refers to a type of fuel injection pump commonly used in diesel engines. Its primary function is to deliver pressurized fuel to the engine’s cylinders at the appropriate time and in the correct amount for combustion. The pump draws fuel from the vehicle’s tank and delivers it through a series of high-pressure lines and injectors that spray the fuel into each cylinder. This process ensures that the engine runs smoothly and efficiently while maintaining proper power output. Without a functioning fuel injection pump, a truck would be unable to operate properly or even start at all.Hawks Parts is a professional Cummins parts wholesale supplier in China, We can provide Genuine/Original, OEM, and Aftermarket quality grades for your choice as well as a one-stop service for you.
