The Wacker Neuson Fuel Pump is a genuine OEM component designed for a wide range of Wacker Neuson ground heaters, hydronic heaters, and indirect air heaters, including the E1250S, E3000, E2200, HI750GM, HI900DGM, HI1000DGM, HIF600, and HSH380 series. Sourced directly from Wacker Neuson, this fuel pump meets the exact design and performance standards of the original part fitted at the factory. It drops in as a direct replacement with no adaptation needed, making it the straightforward choice for service technicians and fleet maintenance crews keeping heating equipment running through demanding cold-weather seasons. Whether you are servicing a diesel hydronic heater or an indirect air heater, part number confirms you are getting the correct pump for the application.
Key Features
- OEM-Matched Flow Rate and Pressure Spec — Built to deliver the precise fuel flow and operating pressure the burner system requires, ensuring clean ignition and stable combustion output.
- Direct-Fit Replacement — Engineered to the original port sizing and mounting configuration so it connects to existing fuel lines and mounting points without rework.
- Broad Heater Series Coverage — Confirmed fitment across E1250S, E1250P, E2200, E3000, HI750GM, HI900DGM, HI1000DGM, HIF600, and HSH380 series machines in both diesel and LP/NG configurations.
- Consistent Fuel Delivery in Cold Conditions — A correctly functioning fuel pump maintains steady fuel supply to the burner; a worn or failing pump causes hard starts, burner lockouts, and inconsistent heat output on the jobsite.
- Fuel System Integrity — As a genuine OEM part, the 5100015664 is built to the sealing and material standards required for safe operation within a pressurized fuel circuit on combustion heating equipment.
The fuel pump is responsible for drawing diesel, propane, or natural gas fuel from the supply and delivering it to the burner assembly at the correct pressure and volume. Without a properly functioning pump, the burner cannot sustain a consistent flame, leading to reduced heat output, nuisance lockouts, or complete failure to ignite — a critical problem when the equipment is being used for ground thawing or wintertime construction heating. Replacing a worn pump promptly restores reliable burner operation and prevents secondary damage caused by fuel starvation or pressure fluctuations within the heating system.
