DESCRIPTION
The Fuel Pump (part number 3936963) is a critical component in the fuel system of a truck. Its main function is to draw fuel from the tank and deliver it to the engine at the correct pressure and flow rate. It typically consists of an electric motor that drives a piston or diaphragm, which creates suction to pull fuel through the inlet line and push it out through the outlet line. The pump is controlled by a relay or electronic module that receives signals from various sensors, such as the throttle position sensor, engine coolant temperature sensor, and oxygen sensor, to optimize fuel delivery for different driving conditions. A malfunctioning fuel pump can cause poor engine performance, hard starting, stalling, or even complete engine failure if not replaced in time.
