Fuel tank drain plug
Power machine fuel tanks include a plug receptacle and a cover for the plug receptacle which seals the plug receptacle from an interior of the fuel tank. A receptacle insert positioned within the plug receptacle allows a fuel plug to be removably secured to the fuel tank. The cover prevents leakage from inside the fuel tank through the plug receptacle, regardless of whether the plug is secured within the receptacle insert, unless the cover has been removed from a sealing position.

a molded cover formed inside the fuel tank above the plug receptacle and sealing an interior of the fuel tank from the plug receptacle;
a receptacle insert positioned inside of the plug receptacle; and
a fuel plug configured to be removably secured within the receptacle insert;
wherein the molded cover prevents leakage from inside the fuel tank through the plug receptacle, regardless of whether the plug is secured within the receptacle insert, unless the molded cover has been removed from a sealing position.
