The Wacker Neuson Injection Line is a genuine OEM component designed for the TH627 indirect-fired air heater. Sourced directly from Wacker Neuson, this part carries the same specifications as the original line fitted at the factory, ensuring accurate fuel delivery geometry and connection compatibility. If your TH627 is showing signs of fuel delivery irregularity or you are completing a fuel system service, replacing the injection line with the correct OEM part is essential for restoring proper heater function.
Key Features
- Genuine OEM Fuel Line Integrity — Manufactured to the exact pressure rating and dimensional spec of the original, maintaining consistent fuel flow to the burner assembly.
- Direct-Fit Installation — Engineered to connect at the same fittings and routing points as the original line on the TH627, making swap-out straightforward for qualified technicians.
- Confirmed TH627 Fitment — Verified for the TH627 indirect-fired air heater (418-02 parts list), so you can order with confidence.
- Consistent Fuel Delivery — A properly functioning injection line maintains the precise fuel metering the burner requires for stable combustion and rated heat output.
- Fuel System Safety — Correct line specification prevents leaks, pressure loss, and combustion faults — critical in a diesel-fired heating application where fuel integrity directly affects safe operation.
The injection line carries pressurized diesel fuel from the pump to the burner nozzle assembly inside the heater. It must maintain a sealed, consistent flow path to allow the burner to atomize fuel correctly and sustain stable combustion. A cracked, kinked, or deteriorated injection line can cause misfires, incomplete combustion, reduced heat output, or fuel leaks — all of which compromise both heater performance and job site safety.
