Filling up at the gas station

I used the little flap diverter form a website and it fixed the filling issues just fine for 19 bucks or so 5 years ago. Called a tank sentry flap. And a gas cap from either slantsixdan or one from Damraider on here or on ebay with a neoprene O ring fixed the right turn spill problem After Market Auto & More Tank Sentry with Flap - Gas Fill Pipe Restrictor for Solving Unleaded Gas Inlet Restrictor Problems on Existing Gas Fill Pipes : Amazon.sg: Automotive
