Keith,
My Eldo tank was leaking along the bottom and I used JB Weld to mend it, and it holds. So, yes, it is fuel resistant. I do know that if you use it on the petcocks, don't plan on ever taking them out again. It's pretty tough stuff, we used to use it in the plant that I worked in to afix plugs into dies that withstood enormous amounts of pressure and I never saw one come loose.

The fiber washers arrived from MG Cycle, so I went out to the garage to check things out. I found out that there were indeed some washers on the petcocks, but they were thinner paper type washers compared to the fiber washers from MG. Thought this was the problem, but realized I have another issue. It appears this petcock is loose fitting as I can wiggle it quite a bit while threading it onto the tank. I had this same problem with the exhaust header nuts and was forced to return them. They have enough thread to spin on, but as soon as it gets tight, it pops loose. Threads on the tank are fine and these are new petcocks. I called Mark and he mentioned using pipe tape or teflon tape on the petcocks to tighten it up, but 1st to get it aligned. Went out to the garage again and got it aligned using 2 new fiber washers and 1 thin paper washer that was on there before. Actually got it to tighten up pretty good without popping loose, but once I poured the gas in, you can see the washer get wet immediately and gas actually works it's way up onto the tank around the cylinder where the threads are, eventually getting wet enough to start dripping down the carb. So, I gather the looseness of the petcock may be allowing that gas to flow down the threads rather easily and the washers can not withstand the wetness coming at them and give way. What are my options to fix this? Is there a type of thread tape that withstands fuel? I would guess the teflon tape would get eaten up pretty quick. Mark mentioned the quick drying JB weld stuff. I have never used it. Will this stuff withstand fuel? Is it a liquid/gel type of glue that I would just smear all over the threads and then install the petcock?
