there is a small vent hole near the top of the gas cap, more or less hidden by the gasket (see photo.)
when your tank's full, the four holes on the bottom of the cap are submerged in gas, and that creates a siphoning effect, and causes the gas to leak out of the vent hole, all over your tank, your leg, your carpet, dog, etc.
if you plug it up with something, you're gonna seal the tank and cause vapor lock, so that won't work.
if you buy an aftermarket cap, like the chevy oil caps, make sure you open it up during rides to vent it, or again, vapor lock.
the best thing to do, is throw that tank in a fire and buy or make one that doesn't look like, well, a crappy china peanut tank.
i've got a pacer moped tank on the way. i'll let you know how that works....
