I have a plastic portable gas tank - the type that has a black plate
containing the hose connection and the gas gauge. Just filled the tank and
as I was placing it on the floor of the garage, I noticed some seepage
around that plate. It does NOT seem to be coming from the socket where the
hose connects, but from the gasket between the plate and the tank. The
tank's 4 years old. Is it common for the gaskets to wear out like that? I
tried snugging the 4 screws a bit, but it only helped slightly.
