I made anchors to keep fuel caps from possibly going through the propeller if left unsecured. For this I used the original factory caps. I ordered an eight-inch long, nylon-coated stainless steel wire rope lanyard with eyelets on both ends from McMaster (item # 30345T3/$1.84) I attached one end to the center screw of the cap and the other to the center of a 1/8” strip of aluminum. This allows easy and unobstructed fueling with the added security.
