The Wacker Neuson Tank Vent Fitting is a genuine OEM component designed for the G100, G120, G150, G180, and G230 series portable generators. This is a direct OEM replacement sourced through authorized Wacker Neuson supply channels, ensuring the part meets the same specifications as the original installed component. Compatible across a wide range of G-series generator configurations — including skid-mount, mobile, cold weather, and custom Tier 3 and Tier 4i builds — part number is the correct replacement for all listed variants. Confirm your model number before ordering to ensure proper fitment.
Key Features
- Genuine OEM Construction — Manufactured to the same material and dimensional tolerances as the original fitting, ensuring a consistent seal and proper fuel tank venting performance.
- Drop-In Replacement — Installs directly into the existing tank port without modification, matching the original connection point and thread spec on G-series generators.
- Broad G-Series Compatibility — Fits G100, G120, G150, G180, and G230 generator models across standard, skid, mobile, cold weather, and custom configurations including Tier 3 and Tier 4i variants.
- Fuel System Integrity — A properly functioning tank vent fitting maintains correct fuel tank pressure balance, supporting consistent fuel delivery and preventing vapor lock or fuel starvation under load.
- Fuel System Safety — A failed or blocked vent fitting can cause pressure buildup or vacuum lock in the fuel tank — replacing it promptly with the correct OEM part maintains safe, controlled venting.
The tank vent fitting allows the fuel tank to breathe by equalizing pressure as fuel is consumed. Without a functioning vent, negative pressure can build inside the tank, restricting fuel flow to the engine and causing power loss or stalling. A cracked, blocked, or missing vent fitting can also allow fuel vapors to escape in an uncontrolled manner. Keeping part number 5200004880 in good condition is a simple but important part of maintaining reliable generator operation.
