This plastic hook is designed to fit a 1980s toyota soarer fuel cap. You use 3M double sided tape to secure it to your inner side of fuel door at a height of your liking. While this was desinged for a toyota soarer , this part should work with all 1980s toyota fuel caps as It is standard as far as I know. These are made for older cars that has no hook for the fuel cap.
Be warned this does not work with screw on fuel cap/lid. If you have screw on type, do not buy this !
