I've discovered that I can recess the fuel cap below the top fuel tank cover if I can find a relatively flush cap that can be fitted to a 2.25" threaded flange. I've got a bayonet style cap now---the "neck" of it is about 1.5" or so long so the top of the cap sits just a little too high to fit it under a cover (it protrudes about 1/2" out of the tank cover as is)


I've thought of going to a Thermos style cap----what do I do for a filler neck? Thought of getting a short section of 2.25x0.125 tube and have it threaded to screw into the flange--then use the smooth inner surface as a mating surface for a 2" thermos style cap.


Any thoughts?
