Abstract

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.

Claims (10)

1. A fuel tank assembly for a power machine, comprising:

a molded fuel tank;

a plug receptacle formed in a bottom portion of the fuel tank;

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.

2. The fuel tank assembly of claim 1 , wherein the plug receptacle is formed in a drain well to allow drainage of fuel in the fuel tank.

3. The fuel tank assembly of claim 1 , wherein the molded fuel tank is made of polymeric material.

4. The fuel tank assembly of claim 3 , wherein the molded fuel tank and molded cover are formed in a same molding process such that the fuel tank and molded cover are formed of a continuous piece of polymeric material.
