Aftermarket gas cap

Hello, I’m looking into any aftermarket gas cap. I’m getting fine sand in my tank and thats what are trails are mostly where we ride I’m sure its also coming from the vent tubes and I’ll put some fixings on them when I get to them if anybody has ideas on covers/filters for vent tubes give me your ideas also if anybody knows a filter system to put over the neck of your gas tank filler neck while filling it at a gas station would be great to. Thanks
