Threaded structure for holding fuel cap during fueling

A method of installing a threaded fuel cap holder, the method comprising:

• guiding at least one groove in a threaded fuel cap holder to mate with at least one flange of an inner side of an exterior fuel panel, wherein the fuel cap holder comprises at least one through hole and at least one groove;
• aligning the at least one through hole in the threaded fuel cap holder with at least one existing hole in the inner side of the exterior fuel panel;
• and
• securing the threaded fuel cap holder to the inner side of the exterior fuel panel by placing at least one fastener through the at least one through hole in the threaded fuel cap holder and into the at least one existing hole in the inner side of the exterior fuel panel.

A method, comprising:

• opening a fuel panel of a vehicle;
• removing a threaded fuel cap from a fuel tube of the vehicle by rotating the fuel cap in a first direction about a longitudinal axis of the fuel tube;
• placing the threaded fuel cap into a threaded receptacle of a threaded fuel cap holder by rotating the fuel cap in a second direction about a longitudinal axis of the threaded receptacle, wherein:
• the second direction is different than the first direction,
• the threaded fuel cap holder is mounted to an inner side of an exterior facing vehicle fuel panel, and
• at least one mount on the inner side of the exterior facing vehicle fuel panel includes at least one groove configured to engage at least one protuberance of the inner side of the exterior facing vehicle fuel panel;
• and
• fueling the vehicle through the fuel tube.
