I discovered a crack about a quarter of an inch long in the float after I removed the sending unit from my tank. Has anyone ever tried to repair one of the brass floats? I have been contemplating trying to soldier the crack but I was worried about any fumes that might be inside the float causing the float to burst when heat is applied. I have a small propane torch but I think a soldering iron would work better as it would keep the heat isolated to just the spot needed repair.

Does anyone have any experience or opinions on whether or not this is worth an attempt? I can't find anyone locally that sells just the float and I do not want to spend $62 for the whole sending unit when all I need is the float.
