Vette Jockey, I agree it could turn out to be a real problem, but I have faith in this forum someone will have an answer. I’m am finding that the old days with Corvette have left the building....... Droop

Laserdude2215, I didn’t think this was going to be an easy problem... I believe in the KISS principal “Keep It Simple Stupid”. This is not happening on these newer Corvettes... Droop

The gasoline probably will still work (don’t go by the smell). I have an old car that sat for over three years and the engine fired right up with the old gas. Now I didn’t high power the engine and fuel mileage sucked but it did run. Before I would slop gasoline; see if it will run!

Larry, I am going to try and start the vehicle just to see if it starts. Put Sea Foam in the fuel last night. Today I’m going to disconnect the fuel line from the fuel rail and bump the starter to clean the fuel out of the lines and get some of the Sea Foam into the fuel system. Let it sit for a day. Check the fuel that came out of the lines, order a new fuel filter to be put in after I get the old fuel out won way or another... My 2014 is a different animal than my 1970 I’m finding out. I’m goin to try and start the vehicle if it shows no water or thickness in the fuel “varnish”. If that is OK we will fire her up tomorrow. Sorry used the wrong word “fire”. Should of used “start”. What do you think?????Droop

Also, how was the car stored during this time? Inside a normal garage, you might be ok. I ran across an old gas can in my garage and put the gas in my lawnmower and it was fine.
Now if the car was outside and experienced the climate changes, you do have an issue with the fuel.

Fuel filter is part of the left tank pump / level sensor assembly. You need access to the top of the tank to remove - that is the tank needs to be dropped!
Pouring anything into the fuel filler now will overflow into the right tank and won't help you for a while until the tanks circulate a bit.
Just thinking - follow the procedure linked in post #9 to empty the left tank, refill with at least 8 gal of gas to dilute. The fresh gas in the left tank will dilute the old gas...

Droop, you could be over thinking this fuel thing. My 2016, 1,055 mile vert had been sitting on the lift due to my battle with cancer. Two weeks ago the lift was lowered and I started it for the first time in 37 months without issue. I let the car idle for about 45 min. before driving it, then just taking it easy. I also cycled the A/C and heat to circulate the coolant everywhere while idleing. I have had no issues and have driven it 3-4 times now. Top tier 93 fuel should last about a year without help. Sta-bil will keep the fuel for about two years if fresh and added to a full tank which I did. Tires set @ 40 PSI and tender plugged in. My garage is climate controlled which helps. You could be opening a larger can of worms by unnecessarily tampering with the fuel system. IF you are asking my advise, I would use some treatment designed to absorb moisture from fuel and a injector cleaner, start the car (yes, it will run) and slowly get it moving on the street. Burn as much of the fuel to about 1/2 tank before adding fresh fuel. Then, IF you have issues, mess with the fuel system. I don't think that you will...

Larry, You are right about the smell...I went with Jimmie Jams Theory first, it worked . We did have to put some fuel components back together before we started the 2014. The fuel we tested turned out to be ok. No moisture and or odor, just ok. Fuel you could run in your lawn mower. We did learn form the guys on the C7 Forum that if you think you have some “Bad Fuel" this is the place to come. All the ideas we received were helpful and we would of tried them in some sort of order. Again thank you for everybody’s help...... Steve

Disconnecting the fuel line at the rail and draining it into a bucket or fuel can is your best bet. For a cleaner event, just run an AN fitting with a length of fuel line over the fender an out of the car. Turn the car to "ON" and get it all out of there.
