Wacker Neuson 5000152110 Vent Tank 1-1/2 Npt

The Wacker Neuson Vent Tank 1-1/2 Npt is a genuine OEM component designed for the G110, G125, and G155 skid-mounted mobile generator series. As a direct factory replacement, part restores proper fuel or fluid tank venting to OEM specification, ensuring the generator operates exactly as designed. This part is confirmed compatible with the G110, G125, and G155 mobile generator models, giving you confidence before you order.

Key Features

• Genuine OEM Construction — Manufactured to Wacker Neuson's original material and thread specifications, ensuring correct 1-1/2 NPT engagement with no leakage at the connection point.
• Correct NPT Thread Size — The 1-1/2 NPT thread profile matches the original tank port exactly, allowing a direct installation without re-tapping or adapter fittings.
• Confirmed Fitment — Verified for the G110, G125, and G155 skid-mounted mobile generator series, covering the full range of these portable power units.
• Maintains Proper Venting Function — A functioning tank vent maintains balanced pressure in the tank, preventing vapor lock and fuel starvation that can cause the generator to run rough or shut down under load.
• Fuel System Safety — A correctly seated, OEM-spec vent fitting prevents uncontrolled fuel vapor release, helping maintain a safe operating environment around the generator.

A tank vent allows air to enter the fuel tank as fuel is consumed, equalizing pressure so the engine receives a steady, uninterrupted fuel supply. Without a properly functioning vent, negative pressure builds inside the tank and restricts fuel flow to the engine — commonly causing hard starting, rough running, or unexpected shutdowns during operation. Replacing a damaged or blocked vent with the correct OEM fitting restores proper fuel system balance and protects engine performance.
