Strong fuel smell
Filled the car up Sunday and parked it in the garage. Today there is a strong odor of gasoline in the garage. No apparent leaks. Billet fuel rails and braided lines under the hood. Checked everything and its dry.
No gas cans stored in the garage. It's coming from the Corvette.
Any suggestions?

It's possible. If it doesn't smell once the fuel level drops a little (leaving the fill pipe empty), it's likely that is the issue.
You have an 01 so it's probably not the crossover pipe issue which affected mostly 04s.
I posted this a while ago which might help track it down:
There seem to have been a lot of fuel leaks recently. I took a look at the book and there are a few connections that could leak.
Start by examining the fuel filter connections next to the exhaust system.
The main fill pipe routes from the cap to the tank. There’s a connector at each end of the fill pipe. One of the early problems was slow filling and GM redesigned the fill pipe to get a better flow.
1. Fuel filler hose
2. Vent pipe
Next check the fuel sender, the aux fuel rear return pipe that connects the jet pump to the left tank and the aux fuel feed rear pipe that connects the left tank to the jet pump at the fuel sender. The FLVV hose routes to the EVAP canister. Finally the crossover pipe connects the two tanks but that’s at the top of the tank so I guess it would be hard to see from below.
1. Auxiliary fuel return rear pipe from the jet pump to the left tank.
2. Fuel return rear pipe.
3. Fuel feed rear pipe at the fuel sender
If the leak doesn't show until the tank is getting full that would be the time when the fuel is starting to fill the right tank via the crossover pipe. It may give a clue.
1. Left fuel tank EVAP pipe.
2. EVAP pipe quick-connect fitting.
3. Right fuel tank EVAP pipe.
4. EVAP pipe quick-connect fitting.
5. Tank crossover hose
6. EVAP pipe quick-connect fitting.
I've never looked in there so not sure how easy it will be to see all these connections but I'd guess you'd need to get the car up on a lift.

Next time you top off, check to see if it smells, again. If it does, open the gas cap door and spin your gas cap a half turn or so. Close the door, and recheck for smell in about an hour, and there is a REAL GOOD possibility, the smell will go away.
I bought a brand new gas cap thinking that was the problem, but it persisted with the new cap. I started spinning the cap, and the smell went away. I put the old cap back on, and the same thing happened.
I don't think it is serious, if you only smell it after a top off. Try this and if persists, maybe a new cap is the answer.

Car is still new to me so I'm trying to fix any issues. Thanks.
