Okay, I'm doing this from memory. Remove the insert cover by loosening and removing the three screws. Lay the new cover face down on something soft not to scratch. Place the outer ring about 30 degrees counterclock wise and so both keyways are just touching the slotted race. Turn clockwise until snug.Tighten one of the set screws. Make sure the other is in so you don't scratch the paint around the fuel door inlet. Put it on the gas hose connector. You have some play. I have the slotted cap so alignment was critical. Turn the entire unit until the holes (3) match. Just start one. Do not try to move the outside ring because it will scratch your paint job. Remember, if your cap has two set screws, tighten the second one. I did it four times before I got it right..... so have patience. The "fisherman"
