The Wacker Neuson Supply Line Complete EMV is a genuine OEM component designed for the FUH35/2/42, FUH70/4/42, FUH70/4/42s, FUH70/6/42s, and FUH70/4/42p CH heater units. As a direct OEM part, the is manufactured to the exact material and dimensional requirements Wacker Neuson specifies for these units, so it integrates with the existing valve and fuel circuit without adaptation. Sourcing the correct supply line assembly is critical on forced-air heaters — a compromised line can disrupt fuel delivery to the solenoid valve and cause unreliable ignition or unsafe fuel handling. Confirm your model number against the fitment list below before ordering to ensure an exact match.
Key Features
- OEM-Grade Fuel Line Integrity — Built to Wacker Neuson's pressure and chemical-resistance requirements for diesel fuel circuits, ensuring the line does not soften, crack, or weep under operating conditions.
- Complete Assembly, Ready to Connect — Supplied as a complete supply line assembly with EMV (solenoid valve) fittings intact, so it connects directly to the existing fuel inlet and valve ports on the heater.
- Verified Fitment Across the FUH Heater Range — Confirmed fit for FUH35/2/42, FUH70/4/42, FUH70/4/42s, FUH70/6/42s, and FUH70/4/42p CH models under part number 5100070840.
- Consistent Fuel Delivery to the Solenoid Valve — A fully sealed, correctly routed supply line maintains steady fuel pressure to the EMV solenoid, supporting reliable burner ignition and consistent heat output across the operating cycle.
- Fuel System Safety — A properly functioning supply line prevents uncontrolled fuel seepage within the heater housing, which is especially important in enclosed job-site environments where forced-air heaters operate near workers and materials.
The supply line complete EMV is the fuel delivery connection between the heater's fuel inlet and its solenoid valve (EMV), carrying diesel under pressure to control combustion. When the solenoid opens on a call for heat, the line must deliver fuel cleanly and without leakage to sustain a stable flame. A worn, cracked, or loosely fitted supply line can starve the burner of fuel, cause intermittent shutdowns, or allow diesel to leak inside the heater cabinet — any of which will take the unit out of service and create a hazard in heated spaces.
