      Gas Tank Cap

      It is beautiful. To bad it doesn,t fit my Fiberglass Racing Tank on my 1966 Triumph. It is set up as a Street Tracker, The cap you sent is the cap I ordered so I will keep it for my next Triumph, Do you know of anyone that sells a chrome cap for a fiberglass tank?

      Nice cap

      This cap fit perfect on my lowbrow deep tunnel p-nut wassell tank. We’ll see how long the cork gasket lasts but I’m happy with it.

      Triumph gas cap

      Bought the cheaper cap first, big mistake.The $28 british made one is 100%. Good service, great website. well run business. Parts are getting too expensive for an ole fart like me. I have bought triumph motorcycles for what i have in the two gas caps!
