[GT182]

I had no problem , except for splash-back when full, when filling my 1st 66 GTO or the 66 Tempest Custom, and for a short time with the 79 Formula Firebird (which wasn't as low as the 66 GTO and Tempest) I had. The filler neck was pretty well centered in the opening for both cars. Not so with the 66 GTO I have now. It seems the gas tank in this one is a replacement. The filler neck opening sits higher in the opening so I have to twist the gas nozzle to the side so it doesn't kick off and stop the flow of gas into the tank. Replacement gas tanks are not always correct for the filler neck.... as we've all found out with many other replacement parts.

You do realize that the gas nozzles are bigger now than back before they were changed for the regular non leaded gas pumps. That happened after I had bought my 79 Formula Firebird. With that car I had to pop out the metal ring that made the filler neck bigger to get the larger nozzle in the neck. As most have probably done already.
