Small engine fuel tank systems and mounting methods

A method for attaching a fuel tank assembly, the method comprising:

• providing a cover configured for covering at least a portion of a combustion engine, the cover comprising a recess configured for receiving a fuel tank therein, a receptacle positioned within the recess against an inner wall of the cover, a first protruding tab extending from the inner wall of the cover at or near the receptacle, and a latch strike extending from the inner wall of the cover at or near the receptacle;
• sliding a fuel tank into position with respect to surrounding components in a non-twisting motion by positioning at least a portion of the fuel tank within the recess, the fuel tank comprising a protruding ear configured for positioning in the receptacle;
• and
• securing the fuel tank in the position with respect to the surrounding components by positioning a retaining clip having a first retaining portion and a latch arm in a blocking position with respect to the receptacle, wherein the first retaining portion is positioned in engagement with the first protruding tab to secure the protruding ear of the fuel tank in the receptacle, and wherein the latch arm is configured for engaging the latch strike to prevent movement of the retaining clip relative to the receptacle, whereby the retaining clip prevents the protruding ear of the fuel tank from being removed from the receptacle.
