Ask and you shall recieve! (Flip Top Gas cap Adapter)
This is about the only Picture I have of the Cap installed at a distance. This was from a long time ago, but this part made it much nicer of an install. You can see the fuel stains from the "radiator hose" seal I had in there before.
I had a piece of Rad. Hose that fit over the original filler tube. It was only like a half an inch tall so it would seal against the cap lid. NO Good! LOL
