The Wacker Neuson is a genuine OEM Fuel Pump designed for the TH627 indirect-fired air heater. Sourced directly from Wacker Neuson, this part is manufactured to the same specification as the original component installed at the factory, ensuring a correct fit within the heater's fuel delivery system. If your TH627 is experiencing weak heat output, hard starting, or inconsistent burner operation, a worn or failed fuel pump is a common cause — and the is the correct direct replacement to restore full performance.
Key Features
- Genuine OEM Fuel Delivery Spec — Manufactured to the exact flow rate and pressure output required by the TH627 burner system, so combustion performance is fully restored from the first start.
- Direct-Fit Replacement — Matches the original mounting footprint, port sizing, and fuel line connections of the stock pump for a straightforward swap with standard tools.
- Confirmed Fitment for the TH627 Indirect-Fired Air Heater — Verified against Wacker Neuson spare parts list 418-02 for the TH627 series, so you can order with confidence.
- Restores Full Heat Output — A correctly functioning fuel pump delivers consistent fuel pressure to the burner, allowing the heater to reach and maintain its rated heat output in demanding cold-weather jobsite conditions.
- Fuel System Safety — Replacing a degraded pump with a genuine OEM unit maintains proper fuel pressure regulation, reducing the risk of fuel leaks or inconsistent combustion that can occur with a failing pump.
The fuel pump is responsible for drawing diesel fuel from the tank and delivering it at a consistent pressure to the burner assembly inside the heater. Without adequate fuel pressure, the burner cannot atomize fuel correctly, leading to hard starts, weak or intermittent heat, and potential burner lockout. Over time, pump diaphragms and internal valves wear, causing pressure drop — replacing the pump with a genuine Wacker Neuson 1000384633 brings fuel delivery back to the specification the TH627 was designed to operate on.
