I have searched high and low, googled, ebayed, looked in the supply stores around here, and still can't find just a plain old style twist on fuel cap. Diameter of the plug is around 1.5" and the 2 tangs that set it in measure about 1-7/8" diameter. I prefer a non-vented cap if possible. I find some that come with the weld-on bung too, but really, all I need is the cap... ??
