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 line installed at the factory, ensuring correct fuel delivery geometry and connection compatibility within the heater's fuel system. If your TH627 is showing signs of uneven heat output, fuel leaks, or burner startup issues, a worn or damaged injection line is a common culprit worth inspecting first.
Key Features
- OEM Fuel Path Integrity — Manufactured to exact internal diameter and pressure rating specs for the TH627 fuel delivery circuit, ensuring consistent fuel flow to the burner assembly.
- Direct-Connect Replacement — Matches the original line routing and end fittings, dropping in without rerouting or adapting existing fuel connections.
- Confirmed TH627 Fitment — Verified for the TH627 indirect-fired air heater (418-02 series), so you can order with confidence.
- Sustained Burner Performance — A properly functioning injection line delivers fuel at the correct pressure and volume, supporting steady, efficient combustion and consistent heat output on the jobsite.
- Fuel System Safety — A cracked or degraded injection line can introduce fuel leaks into the heater body, creating a fire hazard. Replacing with a genuine OEM line restores the integrity of a safety-critical fuel circuit.
The injection line carries diesel fuel from the pump to the burner nozzle assembly inside the heater. It must maintain a sealed, pressure-rated pathway to ensure the burner receives a steady, correctly metered fuel supply for clean ignition and stable combustion. When the line cracks, corrodes, or develops a leak at its fittings, fuel delivery becomes inconsistent — leading to hard starts, burner lockouts, or in more serious cases, fuel escaping into the heater cabinet.
