Drip Guard for Gas Filler Neck

[TRam1]

Anyone ever make or seen a Drip Guard for/attached to the Gas Filler neck?

I will not fill my tank up anymore because it leaks from the cap and drips on my paint. Paint bubble up! Can't find a gasket for the old cap and even then not certain the vent part works properly when gas sloshes on it as going down the road. Doubt its an original so not losing anything. So, I am ordering another cap and hopefully that will help some.

Dumb question I know...
