Default RE: Fuel Barb Soldering Help Please!

I use aviation safety wire on mine as well, and I do like using barbs since a lot of the tubing swells on contact with gas and the barbs are a little insurance against a leak. Some people say don't use Tywraps because they don't put even pressure around the tubing and could actually cause a leak. I have seen that happen...

Some people also say don't use safety wire as it will cut the tubing, but I have never had that problem. I think you would have to be really "yanking and cranking" on the safety wire to make that happen. Years of doing all the plumbing on ultralight airplanes with safety wire and I still have never seen it cut a tube.
