Fuel Injection Pump
The Fuel Injection Pump, also known as the fuel pump, is a critical component of a truck's engine system. It is responsible for delivering fuel to the engine in a precise and controlled manner. The pump pulls fuel from the tank and pressurizes it before sending it to the injectors, which then spray it into the combustion chambers. This process ensures that the engine receives an adequate supply of fuel at all times.
