so I bought another new cap this morning, put it on the truck, and went to get it tested. They failed my brand new cap! I told the guy to run it again, failed. I told him to run it a 3rd time, passed. So where is the real problem? The cap? Don't think so. The testing machine? It's possible. The stupid ass fucktard setting up the test? Most likely. When I confronted the guy with this logic, all he said is "we fail brand new caps all the time, that's why we offer these for sale right here". Are gas cap makers employing standars so loose that theyare running at about a 50% success rate? No. I would lke to see what happens when they put their own caps on the tester. Chances are 50% of them would fail I bet. Rant off, thanks.
