My ‘02 GCAA’s fuel caps are ridiculously tight - sometimes you need a strap wrench. I’ve tried DC4 and oil as a lube (very light coats), but they don’t last more than a few cycles. The Citabria I flew in the past was not anywhere this tight, but it was a ‘73. Any suggestions? Different gasket? Adjust the tangs on the cap?
