On the '65 beetle we have, I always heard that the main culprit wasn't the fuel lines themselves, but the brass flange for the fuel hose being a (not great) press-fit into the zinc carburetor. And that's after the fuel pump, so if that flange comes out the loose end of the hose sprays gasoline all over the engine. It's not uncommon to tie that end of the hose on with some safety wire, just in case.

Makes sense. I'm talking mostly from the perspective of fuel injected Vanagons. Connections generally seem good; it's usually the hoses.
