A new sending unit had a bad float on it that I bought recently. I literally could NOT find a plastic one, but I got a brass one from LMC. It does say Taiwan on the packaging. I was considering before using it to wrap it in sealant tape or coat the seam in red silicone. Would this be wise or will silicone make the float sink dissolve in the gas etc and are there any other measures I could take before install that would insure the float will stay good at least a few years?
