Fuel Tank Isolator Kenworth

The M203116 Fuel Tank Isolator Kenworth is engineered for heavy-duty Kenworth applications where fuel tank stability and vibration control are critical. Offered by Wofford Truck Parts, this part serves as the upper strap or insulator for the fuel-tank mounting system, sized at 36.5″ length and 2.0″ width. It pairs with the lower strap (often part M203118) and other tank support hardware to ensure the fuel tank remains firmly mounted during rough road or load conditions. The isolator’s design reduces metal-to-metal contact, minimizes strap chafing and vibration transfer, and enhances longevity of the mounting system. Cross-references such as K16179315 and K16179322 confirm its compatibility and interchangeability. Ideal for Kenworth models such as C500, T300, T370, T400, T440, T470, T600, T660, T680, T800, T880 and W900, this isolator offers a cost-effective upgrade to extend service life and maintain safe secure tank mounting.
