It is located within the engine\/generator assembly and check valve set on compatible units, providing the metered fuel flow required for burner ignition and sustained heat output.\u003c\/p\u003e\n\n\u003cp\u003eOn models such as the HI750GM and HI750GM HD, the fuel pump works alongside the fuel solenoid, fuel preheater, and burner controller within the machine's fuel delivery circuit. The HI750 series fuel system operates at a specific burner nozzle rate of 4.5 gph at 60 degrees with a solid spray pattern, and proper pump function is necessary to maintain that delivery rate. A failing fuel pump on these units typically presents as inconsistent burner ignition, low heat output, or burner lockout faults traced back to insufficient fuel pressure.\u003c\/p\u003e\n\n\u003cp\u003eThis pump is also used across the E1250P, E1250S, and E3000 engine\/generator platforms, where it serves the same role within the engine\/generator assembly.
