Fliptop gas cap on a Duster

i.e use a flip top cap with a none flip top filler tube (cap to tank)
so that you don't have to find a flip top filler tube for a car that never had one.. etc

other alterntive is to get the filler tube off a flip top cap car and customize it to fit where your none flip top tube went. i don't think you need the spacer if the cap rubber can seal against the end of the correct style tube i.e more than 1 way to skin this cat.

other alternative is to take the seal and spring out of the Flip top cap so it fits over a pre existing locking standard cap. you probably need a spacer

but i think you have to take off the locking cap trim to execute this stealth move
the post on an Australian board about this, is now long gone, so i'm working from memory,
the locking cap may well have been aftermarket replacement for a standard twist on.


pity the actual cap is so expensive
