The Honda 91551-898-000 Tank Cushion Collar is a genuine OEM component designed for a wide range of Honda generators, welder generators, and horizontal shaft engines, including the EB3000, EB5000, EG4000, EG6500, EM5000, EM7000, EU3000, EW140, EW171, EX5500, GX160, GX240, GX340, GX390, and GX620, among others. As a direct Honda OEM part, it carries the same specification as the collar installed at the factory, ensuring it seats correctly in the fuel tank mounting arrangement without any reworking. Honda supersedes parts across serial breaks, so confirm your unit's serial number against the fitment table before ordering.
Key Features
- Genuine OEM Construction — sourced directly from Honda, this collar matches the original specification for correct fit and long service life in the tank cushion assembly.
- Anti-Vibration Function — acts as a cushioning interface at the fuel tank mounting point, absorbing engine and frame vibration to protect the tank and reduce stress on surrounding components.
- Broad Compatibility — listed for Honda generators, inverter generators, welder generators, and GX-series horizontal shaft engines; use the fitment table to confirm the correct application for your machine.
- Serial Number Verification Recommended — Honda revises parts at production breaks, so check your machine's serial number against the compatibility table to ensure part number 91551-898-000 is the right collar for your unit.
The Tank Cushion Collar is a rubber anti-vibration collar that sits at the fuel tank mounting point, isolating the tank from the vibration generated by the engine or generator set during operation. Without a serviceable collar in place, the tank can contact surrounding metal components directly, leading to accelerated wear, unwanted noise, and potential stress cracking at the tank mount over time. Replacing a worn or damaged collar restores the correct cushioned interface and keeps the fuel tank securely and quietly in place.
