Gas Tank Fill Neck
This may sound like a dumb question but...The fill neck on my '72 is as wide as the cap. Is there supposed to be something in the opening to reduce the size to accept a gas pump nozzle? I'm traveling to Ocean City, NJ next month for a show and in NJ you can't pump your own gas. The guys at the Wawa typically have 4 or more cars going at any given time. I always put a micro-fiber towel down before I pump so the handle isn't on the paint and I've never let go of the handle and walked away. To get the tank full, I pull the nozzle out partially and I know the guy at Wawa isn't going to do that.
I found some images of the gas tank and neck and I don't see a "reducer." I kind of like the big opening. My gas gauge under 1/2 tank isn't the most accurate so its easy to pop off the cap and see the fuel level in the tank.
Are there any NJ owners that can comment on their experiences at the gas station?

Gas tanks didn't get the reducer inside the filler neck until 1975 when catalytic converters became standard. Catalytic converters require unleaded fuel to keep from fouling the converter, so to keep people from putting leaded fuel in a car requiring unleaded, unleaded pumps used a smaller diameter nozzle. The reducer prevented larger leaded fuel nozzles from fitting into an unleaded tank.
I've lived my whole life in NJ, and have never had a problem with someone pumping gas into any Corvette. One of my Corvettes had one of those rubber protectors that folds out of the opening when you pump gas, that was put there by a previous owner, but otherwise I've never done anything special at gas stations here with my Corvettes. On some rare occasions I have had an attendant offer me the nozzle, usually when driving my 62.

I suspect it is the same everywhere, but here in CA I have to pull back the rubber sheath on the nozzle so the pump senses its evap recovery is connected, otherwise gas won't flow. I also keep the metal nozzle against the metal filler neck and I always leave a little ullage in the tank. Pretty much every station here is self serve which means I don't have to trust anyone to know what to do.

Here in Oregon, all pumps were by attendant-only until just this year. For the decades that I've lived here, the attendant would always hand me the nozzle to fill up my Corvettes. They really don't want any hassles of scratching the deck or pouring gas all over the rear of a C2 or C3.

I live in NJ and I pump my own gas in my Corvette . When I pull up I tell the attendant that I will pump myself and they just set the pump up and hand me the nozzle.

I don`t know how the pump nozzles are set up , but in Jersey they have a rubber flexible tube on it . It is used to seal against the filler tube of the car to catch the fumes of the fuel. ( LOL ) You will have to pull back and hold the tube for the nozzle to pump the gas because of the wide filler neck on your 72 . I do it all the time on my 69 , no big deal .
