Diesel fuel transfer & priming pumps are also known as lift pumps. Diesel fuel lift pumps are priming pumps that transfer fuel from the tank to the fuel injection system. They are referred to as lift pumps, because in most equipment the tank is located below the engine, the fuel must be lifted from the tank to the engine. Priming pumps also remove air from lines and injectors when starting diesel engines.
