The Wacker Neuson Fuel Pump Complete is a genuine OEM component designed for the E1250, E3000, E2200, and HSH380 series hydronic surface heaters and ground heaters. As a factory-sourced part, the is manufactured to the exact specifications required by Wacker Neuson, ensuring proper fuel delivery and reliable burner operation across the full range of compatible units. Fitment covers diesel, natural gas, and propane-configured models within the E1250S, E1250P, E2200, E3000, HSH380S, and HSH380B families. When your heater's fuel supply is compromised, installing the correct OEM pump is the fastest path back to full heating output.
Key Features
- Correct Flow and Pressure Spec — Genuine OEM construction ensures the pump delivers fuel at the precise pressure and flow rate the burner assembly requires, not a close approximation.
- Direct-Swap Installation — Matches the original mounting configuration and port sizing of the factory pump, so the 5200018120 installs without modification to fuel lines or mounting hardware.
- Broad Series Compatibility — Confirmed fitment across E1250S, E1250P, E2200, E3000, HSH380S, and HSH380B models in diesel, LP, and natural gas configurations.
- Sustained Heating Output — A properly functioning fuel pump maintains consistent burner ignition and heat output; a failing pump causes misfires, weak heat, or complete shutdown on the coldest days when the equipment is needed most.
- Fuel System Safety — Replacing a worn or leaking fuel pump with a genuine OEM part maintains the integrity of the fuel delivery circuit, preventing uncontrolled fuel flow that can create hazardous conditions in enclosed or occupied job areas.
The fuel pump is responsible for drawing fuel from the supply tank and delivering it to the burner at a controlled pressure. In hydronic heaters and ground heaters like the E1250, E3000, and HSH380 series, consistent fuel delivery is critical — the burner relies on a steady, correctly pressurized supply to ignite cleanly and maintain the output temperature needed to heat fluid through the system. When the fuel pump weakens or fails, the result is hard starting, inconsistent flame, reduced heat output, or a complete burner lockout. Replacing it with the correct OEM part restores full system operation.
