C7 Corvette fueling problem
I purchased my 2014 veto in 2017. The gas lid door failed closed and was repaired. In my next fueling the fuel nozzle would shut off after a few gallons. As this continued, brought it to dealer and they replaced anti-siphon tube. Problem has continued. Dealer replaced tube again after six months, problem fueling has continued. It happens at at least half the gas stations. Dealer says fill tank slowly to avoid problem, which works but takes about ten minutes to fill a nearly empty tank.

Somethings going on there with your fuel filler. I'd get Chevrolet Customer Support involved. It should not take 10 minutes to fill your fuel tank with gasoline. That's just wrong.

Many corvettes keep shutting off the pump while fueling. Turn or change the angle of the fuel flowing into the neck and it should be fine. Different pump nozzles cause issues. Not a big deal at all.

FWIW, my '14 NEVER had this problem until I had the anti-siphon grid recall done. Now, it bothers me quite often, sometimes randomly: every time on a few of the normal pumps I frequent. I try to avoid those unless there's a wait at the station. I turn the pump upside-down to start, and sometimes after a few gallons, I can turn it back down(right-side-up) to finish.
I wish I had never had the recall performed, but I don't really want to pull the fuel filler neck out myself and pull the grid out at this point.

I have had that happen with the last three Chevys I’ve owned. It happened with my 2010 Tahoe and my 2012 2500HD. And now it happens with my 2017 Z06.
I think it also has a bit to do with the brand of gas too, or more specifically the type of pump and vapor recovery system. I can’t leave a pump unattended at 76 stations, in any of the vehicles, but have zero problems at Chevron.

Plus sometimes you just have to stand there and hold the trigger inside the handle. Or try pushing it in more at a different angle. With most cars, you can set it and forget it. Not so with the Vette. You have to play around with it a little sometimes.

90% of the time I have to fiddle with the angle and pull the trigger several times. Even on pumps that allow constant flow, it still stops at almost exactly half. I thought that might be a track feature. Either way, filling up the vette is tricky.

Here in ny unless it is an attended pump there is no lock and you need to trigger to fill. Always stuck holding the nozzle. Did notice the vette was a little more sensitive but only filled it twice so far
on another note the lack of cap always bothered me. Once with an explorer they’re was a small detent on a nozzle. Went to pump and could not get nozzle out. AAA came and wound up ripping the whole filler assembly off the car. Seems there’s a small flap valve that caught the nozzle and locked it in. I don’t know the anatomy of the vette nozzle but the ford flap is from the top and to get the nozzle out a snake on top would be needed. Rippling our the nozzle meant we drove home from Vermont with a rag stuffed in the filler. Like a giant motatov cocktail

Happens to my 17GS about every 4th or 5th fill up. Not sure why. Not consistent at all. I just resort to setting the angle that gets the flow going uninterrupted and just manually hold the trigger versus using the clip hold.

turn handle 180* and it fills fine.

I'm not sure if they made any changes on the 2018 to fix this but I haven't had this problem yet with mine and I've filled up the tank quite a bit (I never let it get to empty, I top it up often) I've used the fastest and the slowest setting on the pump and either way works fine for me.

You should always fill your tank on the slowest setting.
"Most nozzles are set to pump gas at three speeds – slow, medium, and fast. Pumping at high speeds releases more gasoline vapors, which your nozzle pulls back in with a vapor recovery system most pumps are outfitted with. This means you could be paying for more gas than you receive. Pumping at a slower rate releases fewer vapors, which means you’re receiving more of the gas that you paid for."

My 14 Stingray would shut off early about 1/4 of the time. I usually use one of the same 3 stations.
My 18 Grand Sport has shut off early 2 of the 3 times I have filled it so far.
Usually rotating the handle 90 degrees solves it. However it is still inconvenient.
Thing is my 17 F-150 does the same. With it, is much more than a pain, as its a 36 gallon tank and it does it 75% of the time.
Same cap-less fuel fill like the Grand Sport.

I spoke too soon yesterday, and I filled up last night with the tank close to empty and after only about 2 gallons pumped in, the pump shut off (the nozzle was locked on the highest setting) I started pumping again with it on the lowest setting and it worked fine from there.

Unless you have something you MUST do when it's filling, turning the nozzle has worked for me from my first C7 in October 2013 to now! It's about a 25% occurrence so the first time it clicks off, I turn the handle 90 degrees, use full flow with my hand on the lever and it fills quickly! In all these years it has NOT failed to shut off when full BUT I'm there holding the level IF NEEDED.
No longer frustrating, it's my calm MO!
Wish I only had that simple workaround with Microsoft etc products! And Bill Gates is the richest guy in the World!

Something to look for.... I went to refuel last week and did not notice the pump lever was stuck in the on position, and when I pushed the fuel grade button fuel started coming out... Just lucky that I had the nozzle pointed away from the fender....and was able to get the lever pulled back to the off position...
