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 unit installed at the factory, ensuring a correct, trouble-free installation. If your TH627 heater is experiencing fuel delivery issues or showing signs of a damaged or worn injection line, replacing it with the correct OEM part is the straightforward path back to full heating performance.
Key Features
- Genuine OEM Construction — Manufactured to the exact pressure rating and dimensional tolerances required for fuel injection lines, eliminating the risk of misfit or premature failure in a high-pressure fuel circuit.
- Direct-Fit Replacement — Engineered to connect directly to the existing fittings on the TH627 fuel system with no reworking of line ends or mounting points.
- Confirmed TH627 Fitment — Verified for the TH627 indirect-fired air heater (418-02), so you can order with confidence that this is the correct line for your machine.
- Consistent Fuel Delivery — A properly seated injection line maintains the precise fuel flow the burner assembly depends on for stable, consistent heat output across the operating range.
- Fuel System Safety — Injection lines carry pressurized diesel fuel; using a correctly rated OEM line is critical to preventing leaks that could create fire or hazardous vapor conditions on the worksite.
The injection line carries pressurized diesel fuel from the pump to the burner nozzle assembly inside an indirect-fired air heater. It must maintain a sealed, leak-free connection at both ends to deliver the precise fuel volume the burner requires for controlled combustion. A cracked, kinked, or loose injection line will cause erratic heat output, hard starting, or a complete burner lockout — and because the line operates under fuel pressure, any breach also presents a serious fire risk that warrants immediate replacement.
