Flip-Top Gas Cap Seals
I have been working on my 1966 Barracuda restoration for some time. My latest stage is reworking the fuel tank. As I am planning on converting to fuel injection at some point in the future, I choose to replace the original fuel tank with one that included an in-tank fuel pump with return lines. When I went to remove the old fuel tank, I discovered the original had developed some pin holes as well as discovering the original filler neck was crusty with rust as corrosion as well. I also was planning on converting the gas cap to a flip top cap in the process and had purchased an original flip-top gas cap and one of the adapters made by FABO Member DAMRAIDER a number of years ago.
As I started to start putting all the bits together, I noticed the gas cap rubber gasket had multiple cracks and splits in it and started searching for a replacement seal. I was hoping to find one made out of Viton so it would be resistant to modern fuels but after searching multiple sites, all I could find was re-poped gas caps. I also found a number of threads on this site where people were looking for a replacement seal but never saw anyone state they were successful in sourcing one.
I decided to look for a source for the Viton material and make one for it as well to seal between the gas cap adapter and body and upgrade the original white foam gasket for the filler neck to the body. I am attaching a few pictures of the results below.
Flip-Top Gas Cap
New Seal installed on Cap. Original seal on right.
Original seal on left. New seal on right.
Gas Cap Adapter and new seals.
If anyone is interested in any of these items, I still have some of the Viton material to make a few more. Not really interested in doing this as a business but will help others out if there is an interest. All seals are CNC cut from 1/16” Viton. The Viton sheet is fairly expensive so thinking about pricing them around $15 shipping included for US Addresses for one gasket and $30 for a set including 1 flip top cap seal, 2 adapter seals, and one body seal.
Send me a PM if you are interested.
Thanks!
