So, I'm guessing a loose connection or a short in the fuel-gauge, or a defective gauge. I'll try & get a service appointment tomorrow.

I think it was simply a bad part. I now have close to 4k miles & have been using the same premium gas from Safeway, Valero, Arco, 76, etc., as I was initially using from the same stations.
The problem has not resurfaced.

It's the gas. I believe something similar happened in FL last year also. Upgrading the FSU may reduce the number of occurences, but the root cause is still the gas. Most of the rage expressed here should be directed at the refiners, not GM, Chevrolet, or Dave Hill.

Never had the FSU problem with my 03 coupe. Have yet to experience this problem with my 05 coupe. I've used nothing but Sunoco 94 Ultra gasoline in both rides.

I also had the same message at around 650 miles. Car now has 1200 miles and message has not returned. Mobil premium and sunoco ultra used.....I first thought my gauge was showing empty because the g-force was pushing all the gas back 
but I guess a bad part makes more sense. Does this effect anything else besides the fuel gauge?
Nice site by the way. Glad you folks are here

Unless the issue is the engine falling out of the car, you can count on a first year problem plauging every model year of the car's run.

I had just filled the tank with the highest octane Mobil available at most local Southern California stations (91, I believe). Nice to know that my month old car will have to have the fuel tank pulled to replace a part that was a common problem in the C5...

Same FSU Problem
My engine warning light came on at just under 700 miles followed shortly thereafter by the fuel gauge going dead and the message "Service Fuel System" coming on in the DIC. After re-starting the car, the gauge came back, but the engine warning light stayed on. After several more restarts, the engine warning light went off too. Then the whole sequence would happen again randomly as I drove around. Took it to the dealer and they first re-loaded the software which didn't work. Now they are in the process of replacing the FSU. According to the service manager, the gas should not impact the FSU, just impair performance (some pinging and loss of power) if you use the generic stuff like COSTCO. He did say that Chevron or other branded gas would be good to use every once in awhile to help keep the fuel injectors clean. He also said the replacement FSU was supposed to have gold tipped leads which might help prevent a reoccurrence, but he also said he wasn't sure whether the one installed during production had the same leads. Worse thing though was while my car was waiting to be fixed, the paint was scratched so now they also have to send it out to a body shop to have that fixed (At least they called to tell me about it instead of trying to slip it by me) In the meantime they gave me one of those huge GM full cab pick-ups as a loner. Will keep you guys posted after the FSU is replaced.
