The combination of the filler neck being on the outside of the quarter along with the gasket being between on the outside of the quarter pushing it out even further could account for all of the discrepancy.
Nope. The gasket is supposed to be just like it is. He’s got the wrong cap. He might be able to tighten those screws a bit, but that does not account for the cap being a 1/2” out.
My car is missing the gasket, it’s supposed to be there.
