As for fuel line, I'm not sure how you guys are getting 3/16" I.D tubing to fit over the petcock/carburetor barbed nipples. I use 1/4" I.D (inside diameter) fuel line and it does fine even without clamps, but I do clamp them just for security.
Yes Tom, those are metric pipe threads equivalent to a US 3/8" per se. The poster asking is in Australia and they're metric down-under, so close enough to 3/8" with metric thread pitch.

As for using 3/16" on the larger barbs, just heat tubing up and add a drop of oil to it....slips right on and no need for clamps as well. You pretty much need a razor knife to remove it however.

Nothing is out of my realm,
if it doesn't fit, make it fit! Beer is the answer....what was the question?
A sense of humor costs nothing, why don't people use them more often?
