Looking for a lead to find piece for gas cap 1971

[MikeL]

I'm looking to see if anyone has or knows where I can find a good used parts source (Junk Yard) that might have this piece I need for my 1971 U.S. Gas cap. Or for that matter any suggestions on finding a replacement or using something different. I'm restoring the evaporator loss system on my 1971 and I'm using my original gas thank. It has tow vent holes in the top and one goes up the the gas cap.

It's been a while since I removed that but I seem to recall it's a pipe thread. You may find it in the plumbing section of ACE.

Thanks for the reply, It's along story but after checking the auto zone, lowes, Ace hardware and Harbor Freight, I came home defeated only to look on my work bench and find a small air blower hooked up to my air system. I took the rubber nipple off and the small brass piece looked like it would fit. So I took it off and low and behold it does fit and will work.
