I hope I'm not crowing too soon about having solved the fuel leak. After several apparent "fixes" that eventually failed, mostly tightening or adding clamps, I finally decided that the real problem wasn't the clamping, it was the hose. I remember that there was a tiny bit of rubber on the brass barb when I got the hose off for the frame brace installation. Apparently, the elasticity of the hose isn't enough to fill in that gap, thus the intermittent leakage. I bit the bullet, so to speak, and got some 100 psi rated 5/16" F.I. hose, Dayco p/n 80079, and put it on with some screw type hose clamps. They weren't worm drive clamps, although I'd have no hesitation to use those again. I used the entire 18 inches of hose so that I could stand to lose an inch or two in future. It doesn't have the fabric outer casing but I don't think I care.
