What Does a Lift Pump Do for Cummins 3.9 8.3?
The Cummins 3.9 and 8.3 engines are diesel engines that require a lift pump to supply fuel to the engine. The lift pump's main function is to deliver fuel from the fuel tank to the injection pump at the correct pressure, ensuring proper fuel flow to the engine.
The lift pump draws fuel from the fuel tank and delivers it to the injection pump, which then supplies the fuel to the engine's combustion chambers. The lift pump helps to ensure that the injection pump always has a steady supply of fuel, even when the fuel tank is low.
In addition to delivering fuel, the lift pump also helps to remove any air that may have entered the fuel system. This is important because air in the fuel system can cause the engine to run poorly or even stall.
