The fuel supply pump, part number 04238005, is a component in the fuel delivery system for the Deutz F4L912 engine. Its primary function is to draw diesel fuel from the tank and deliver it at the required pressure to the fuel injection system. This process ensures the engine receives a constant flow of fuel, which is necessary for consistent combustion and engine performance during operation.
This component is compatible with various manlift models, including the JLG 1044C-54 Highlander, 110HX, 33RTS, 40 RTS, 60H, and 80HX, as well as corresponding units from Deutz, Ford, and LULL. It is specifically engineered to interface with the mechanical requirements of the Deutz F4L912 engine series. The pump is mounted to the engine block to facilitate the mechanical actuation required for fuel transfer.
In diesel engines, the fuel supply pump acts as the primary link between the fuel storage tank and the high-pressure injection system. By maintaining correct fuel pressure and flow, the pump prevents air locks and starvation within the fuel lines, which supports stable idle and load-bearing power output for heavy machinery.
