When one of my truck's 40 gallon grease tanks' air release valves gets clogged the metal sides of the tank suck in, and out sometimes, and they release a lot of air pressure if you open the gas cap. Anyone know if this is a problem or if there is any danger of an explosion or anything? The tank that does this is admittedly a cheap Golden Fuel Systems tank. Thanks.
