Note: Any low-permeation tank may become pressurized when exposed to direct sunlight or any other source of heat. Under these conditions you may see the tank expand or bulge. Do not place the tank in a confined area that prevents this normal expansion. Pressurized low-permeation fuel system components require a thread sealant specifically designed for the unique conditions they create to maintain a leak-proof seal at their threaded connections. Tape-type thread sealants will not withstand the pressurized conditions potentially created within low-permeation systems. Permatex Aviation Form-A-Gasket No. 3, Model 13630512, is recommended for all low-permeation fuel system threaded connections.
