I had no problems with any gas leaks and then a couple of weeks ago, I put in about 7 gallons of gas and started car in garage.
The next weekend I came out and smelled Strong gas and looked underneath and seen a spot underneath differential. I cleaned it up thinking Maybe some spilled in the filling process.
I came out 2 weeks later today and there is a spot underneath the differential and by both wheels. I first thought maybe both rear calipers started leaking, but it seems it gas wicking down the rear spring somehow..
About 5 years ago I put in a new gas tank and sending unit from corvette America I think.
Could this be a gas tank failure alreqdy or are there lines centrally located that could have failed ?
it does seem to have started and the heaviest right and the where the spring mounts to underneath differential.
I already drained the gas and preparing for the sucky removal of everything to look.
Thanks for any help
Check the usual suspects. Start with the rubber fuel lines from the sender to the steel fuel line that is mounted to the frame. Next, inspect the O-ring between the tank and sender. Does the inside of the tank show any signs of rust? Hope it's not the steel fuel line on the frame. Good luck. Jerry

no rust apparent in the tank and thank God, since it's relatively new.
it's been a while, can I get a view of most of these locations you mentioned by just removing the spare tire and carrier?
thanks
Could just be the sending unit gasket. Start with pulling the spare tire carrier. Perhaps you will find it that quickly. Perhaps not. But you have to start somewhere.
Yes, remove the spare tire cover. The front bolts of the carrier can be a pain. Start the process by putting Liquid Wrench or Kroil on the bolts. Since you have already removed the fuel from the tank, I would change the line from the tank to the rail fuel line as a precaution. Get rubber fuel injection line. It is overkill, but at a buck or two a foot, is well worth the price. If you have to replace the sender O-ring, make sure you get a good quality one. Try Dr. Rebuild. The C-2 AIM indicates that the O-ring should be soaked in conventional motor oil for a few hours before installation. That has always worked for me. Lastly, once the sender is changed, add fuel in increments. Leave the tire carrier off until you are sure the sender is leak free. Jerry
