65 barracuda gas fill issue

That looks like a pretty good way to solve something. So far looks like fuel restrictor. I had 2 65 barracudas at the same time in late 60’s and early 70’s. I just don’t remember this

Yeah, wasn't as much of a problem then- the gas pumps didn't run as fast I'm told. The nozzles for regular were bigger and they pumped slower.
