'73 Fuel Cap???
I just purchased my '73. I have been hunting a gas smell in the garage and removed the fuel cap for the first time to inspect it. When I removed it the cork gasket fell out of the cap and I could tell that it was not sealing properly. In prior posts I read that the original gas caps were stamped if they were vented or non-vented depending on vehicle year. This cap is not stamped however, there is a small whole that goes though a plate inside the cap so I'm assuming this is a vented cap and not proper for my year. I'm pretty certain this is a cheap pot metal/chrome aftermarket cap because the cork gasket falls out when replacing the cap and it is not stamped. I assume Chevrolet had a rubber gasket in their caps that does not fall out. Could someone snap a couple pictures of their original style caps for a '73 (top and bottom)? Also, does anyone know if Chevrolet still sells the OEM gas caps, or who sells a good replacement cap? Thanks!!!

1973 would have a sealed system due to the EVAP system. Any of the Corvette vendors on this site can supply the correct cap and they typically have a picture of the cap.

Hope you have many "miles of smiles" with the 73'.
