looking forward to purchasing a Duramax lift pump

So, are you looking forward to purchasing a lift pump for a Duramax engine? Duramax engines are one of the most responsive engines to an aftermarket lift pump.

The reason is that these engines don't feature a lift pump to help them supply fuel to the engine. In fact, the engines rely on a CP3 or CP4 pump to pull fuel from the tank to the engine. However, since fuel is usually under constant suction, this causes excessive wear of the injection pump and injectors.

  • CP3 or CP4 Pump: Since Duramax engines do not include lift pumps, the only way to get fuel from the fuel tank to the engine is via the CP3 or CP4 pump which is a high-pressure fuel pump installed in the engines. The pump is also referred to as an injection pump, and its main task is to ensure constant pressure in the high-pressure fuel rail which feeds the injectors.

How to Install Duramax lift pump

The installing of the lift pump in your Duramax may or may not be easy for you. If you already have some experience with fittings in cars or small repairs of the truck, it is pretty easy for you then.
