Larry Morphew Hi Larry, Any body shop with a plastic welder for bumpers, etc, should be able to weld up the leak in your tank. No idea where you might buy another, other than at an RV salvage yard. Never tried the NAPA stuff but I have great doubts about it sticking to common structural plastics. I'd certainly not put it on the tank before checking out welding, as the goop could very well mess up the defect so that welding is impossible. If the defect is a puncture or similar localized leak, it can also be sealed with a bolt, nut, rubber washer and fender washer assembly. This assumes you can somehow get the nut positioned in the tank (gas gauge opening, perhaps?) Simply drill the fault, assemble a fender washer and neoprene washer in that order on the bolt, pass it through the hole in the tank and assemble a similar sandwich along with a nut on the other side. When you tighten the assembly, the rubber will seal the assembly tightly. I've used this technique on large HDPE farm-type tanks on more than one occasion. Make sure you get neoprene sheeting to cut the washers out of, as it is the only commonly available rubber that is gas resistant. John |
