The Wacker Neuson Fuel Pump is a genuine OEM component designed for the HI110HD D, HI200D, and HI200HD D series diesel indirect air heaters. As a direct OEM replacement, this fuel pump is built to the exact specifications of the original part, ensuring a correct, hassle-free installation in your Wacker Neuson HI-series heater. Sourced directly from Wacker Neuson, part number carries the same engineering standards as the pump that left the factory. If your indirect air heater is struggling to maintain flame, cycling off unexpectedly, or failing to ignite, replacing the fuel pump is a common and proven fix.
Key Features
- OEM-Matched Fuel Delivery Specs — Engineered to the exact pressure and flow rate required by Wacker Neuson HI-series diesel burner assemblies, so combustion stays consistent and efficient.
- Drop-In Replacement — Matches the original mounting configuration and fuel line connections of the HI110HD D, HI200D, and HI200HD D, making installation straightforward with standard hand tools.
- Broad HI-Series Compatibility — Confirmed fitment across HI110HD D, HI200D, and HI200HD D diesel indirect air heater models, covering a wide range of Wacker Neuson heating equipment.
- Restored Heating Output — A correctly functioning fuel pump maintains the steady fuel supply the burner needs to reach and hold target heat output; a worn or failing pump causes erratic burner cycling, weak heat, or complete ignition failure.
- Fuel System Integrity — As a genuine OEM part, this pump meets the fuel-system sealing and pressure standards required for safe, compliant operation of diesel-fired heating equipment.
The fuel pump in a diesel indirect air heater is responsible for drawing fuel from the tank and delivering it to the burner assembly at a consistent, controlled pressure. Without adequate fuel supply, the burner cannot sustain combustion, leading to weak heat output, frequent shutdowns, or a complete failure to ignite. Over time, pump diaphragms and internal valves wear, reducing pressure and flow — replacing the pump with a correct OEM unit like the Wacker Neuson 5000186832 restores the heater to full, dependable operation.
