The Wacker Neuson is a genuine OEM Fuel Tank Cap designed for Wacker Neuson HI-series diesel indirect air heaters. This is a direct OEM replacement sourced through authorized Wacker Neuson supply channels, ensuring you receive the exact part specified for your machine. Confirmed fitment spans a wide range of HI-series heaters including the HI110D, HI110HD D, HI200D, HI200HD D, HI300D, HI35, HI90, and HI90HD, as well as HD50 and HD70 models. Keep your heater fueled and sealed properly with the correct cap for your unit.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's exact thread pitch and seal specification, ensuring a fuel-tight closure that prevents leaks and fuel contamination on diesel-powered heaters.
- Direct Drop-In Replacement — Threads directly onto the OEM fuel tank filler neck with no reworking or adaptation needed, restoring the original closure mechanism as it came from the factory.
- Broad HI-Series Compatibility — Fits HI35, HI90, HI90HD, HI110D, HI110HD D, HI200D, HI200HD D, HI300D, HD50, and HD70 diesel indirect air heaters — one part number covering a wide range of Wacker Neuson heating equipment.
- Fuel System Protection — A properly sealing tank cap prevents diesel from spilling during transport and keeps moisture, dust, and debris out of the fuel supply, protecting injectors and the burner assembly from contamination-related damage.
- Fuel Handling Safety — On diesel-fueled heating equipment, a correctly seated tank cap is critical to preventing fuel vapors and spillage near the burner — replacing a cracked, stripped, or missing cap restores a key safety barrier.
The fuel tank cap seals the diesel fuel tank on indirect air heaters, keeping the fuel supply contained and free from contamination during operation and transport. A damaged or missing cap allows moisture, dirt, and debris to enter the tank, which can clog fuel filters, foul injectors, and cause unreliable burner performance — especially in cold-weather jobsite conditions where these heaters are most heavily used. Replacing a worn or damaged cap with the correct OEM part is a low-cost fix that protects the broader fuel system and keeps the heater running consistently through demanding heating seasons.
