I have a 2012 Grand Sport convertible and it's my turn to experience the common fuel tank problems. I noticed the fuel gauge stopping at half when I filled up. So it's been at the Chevy dealer for 10 days now waiting for parts. I bought the car on Carvana a year ago (found it in Carlisle Blue) and I was smart to buy their comprehensive warranty. So this will be covered, less a $350 deductible for taking it to a dealership.
But the problem is that they cannot locate the FUEL TANK CROSSOVER TUBE - P/N 15223882 through GM.
Does anyone know if this OEM part is still available? They won't warranty the work unless they use all GM OEM parts. And for all of you guys that did this job yourself, without a lift, God bless you! I'm 70 now, and after 13 Corvettes in 50 years, I just want to put air in the tires.

I appreciate your reluctance to wrestle with the fuel tanks and associated piping.
I’m close to your age and tackled this myself last Christmas with the aid of a plastic creeper, a small transmission jack and a Chiropractor.
Finding new parts to retain the GM dealer’s warrantee may be challenging.
You may want to search around yourself for the GM cross tube.
The 15223882 part number has been replaced by 19436041.
If the car has not yet been dismantled it may be worth trying to find a local Corvette specialist which would give you the choice of using used parts, if required.
Ideally it may be worth replacing the drivers fuel pump at the same time as the Passenger side Fuel Tank Fuel Pump Module Kit and Fuel Level Sensor as most of the labor is already done.
In case you change your mind on trying the project yourself.

Thanks, but as long as I have that Carvana (SilverRock) extended warranty and they’ve already agreed to cover the entire repair, my hands are staying clean on this one. All of the fuel pumps, level sensors, tubes, etc. are covered and at the dealership. They were only waiting for the crossover tube (and it must be new to be covered under the GM warranty).
Well, I stopped by there today and after talking cars with the parts department manager, he got on the computer and the phone. He found an NOS tube and they will have it in three business days. Yeah!
This reminds me of what we all went through in the 70’s and 80’s trying to find original parts my mid-years, especially big blocks. There were no repro businesses then, and it took years to find some parts. Now, everybody has everything for C1 through C3’s.
That's great news. I would love to know where he found it. I've got a 2013 with the same issue - GM OEM 2003-2013 GM Connector Pipe - 19436041 is seemingly unavailable. My car is apart also. I see your old pipe on the ground under your car... any chance you have the name of the NOS tube?

I stopped by the dealership two days ago and saw my new OEM connector pipe in the box onto the car, with the old one still laying on the floor. So it was delivered just as the parts manager said it would be. So after I was done sneaking out in the shop to check on it and take my pictures, I went to the service advisor, who of course lied and said they were “waiting on the part”. I informed him that the part was already there. I loved the expression on his face then.
Today is Friday and I expected it to be ready, but now I’m being told that the technician had to (ready for this?) drop the transmission in order to reinstall the tanks and crossover tube. I have never read about that having to be done. So all I can assume is that it’s to prevent breaking the connectors on the crossover tube when the transmission is blocking things.
It’s been three weeks since they’ve had my car, so when or if I get it back next week, I’ll find out where the parts manager was able to obtain that crossover tube and what the new part number is on it. I was told that when they change sources of a part, the part number changes.
I thought it was funny in your earlier pictures that they didn’t drop the rear end. I figured they were trying to save on time since it was warranty work and not a cash job. Huge difference in billable labor between dropping the rear end and just dropping the tanks!! LOL!! Hopefully they get your car back to you soon.
Someone correct me if I'm wrong but if all that the dealer did was replace the passenger side venturi fuel pump Assy AND at the end of the day removed the transmission, rear end and torque tube there was no reason to separate the right & left tanks for this job. Just drop both tanks as a unit and R&R the passenger side venturi fuel pump assy.
From all the videos I have watched on this subject and pictures the driver's side tank fuel pump and passenger side venturi fuel pump can both be removed and replaced without disconnecting the crossover tube PROVIDING the transmission, rear end and torque tube are removed and both tanks dropped as one unit assy.

This job is being completely covered under warranty by Carvana’s SilverRock Insurance Company. I only pay $350 because I wanted a dealer to do the job. But GM’s policy on this is to completely replace both sensors, the pump, the crossover tube, and the internal d/s tank plastic intake tube. Everything except the fuel tanks is new. Nothing else gets reused. And I’m sure not complaining! And while everything is down, i’m going to see if I can get them to replace the automatic shifter cable and charge me a minimum labor amount.

tanks, crossover, and evap tube can not be removed as an assembly. crossover goes through an opening in each frame rail.
Just did this job a couple weeks ago I'm 63 and my back is still sore
My deepest sympathies. When I looked out into the dealer’s shop and saw everything on the floor, I was in shock. Then when I saw the service department invoice today, when I picked it up, that was a bigger shock! Good thing I bought the warranty!!! I’ll post it here.
Well after nearly a month at the dealership, I finally got it back. I've been working on Corvettes for 50 years, but this is one job that I would NOT do myself. The smartest thing I did was to buy the extended warranty when I bought the 2012 Grand Sport convertible (in Carlisle Blue) a year ago from Carvana. Repairs would be $100 deductible at just about any shop, but I gladly paid the $350 deductible to bring it to the dealership.
But check out what this total job cost .... OVER $5,000! The dealer is only permitted to use new OEM GM parts and must replace everything on this repair. And you can see the technicians diagnostic tests, where both sensors were bad. So in addition to the exhaust system, they pulled the transmission, underbody pan, and the torque tube. And if anyone has trouble finding the crossover tube (listed as "hose"?) there's the part number and $500 cost.
I would just discount the car and sell it if this was my mess to deal with.
What mess? You would sell your Corvette if it had a common C6 repair done, under warranty? If you’ve owned Corvettes before, you must have lost a fortune bailing out of them so easily!
Try to find a 2012 Carlisle Blue Grand Sport convertible (1of 118) with only 10,900 miles and in #1 show condition. If I ever sell it, I’ll get a premium for that.

My car is a 2012 GS with low mileage and no warranty remaining so yes I would sell the car before paying $5K to repair what is NOT a common C6 repair. I have owned 10 Vettes over the last 30 plus years and completed three frame off restorations (65 x2 & 69) so I know a thing or two about wrenching on Vettes. Every Corvette is one of something and really means nothing other than to the owner.
So yes I would discount the car and sell it before dropping $5K into a repair of this type, it's just a used Chevy.

If you read my post, you’ll see that I HAVE a comprehensive warranty. With either a $100 or a $350 deductible (if I choose a dealer repair). So I didn’t drop $5,000. SilverRock Insurance did. And if others here didn’t convince you that it’s a frequent repair, like the automatic shifter cable grommet failure, then look up the threads on these.
I'm 70 and have owned 13 Corvettes now over the past 50+ years. Two were Top Fight cars. I do all my own work, except an alignment.
Hopefully, you won’t need to replace the C6’s tires soon, or it will be time for #11.

Tires in two years will be next on my list of things to do, complete fluid change this year or in the spring, I have no issues maintaining a car just some things I'm not willing to do or mess with. I also understand this repair cost you little to nothing due to the Carvana warranty insurance you purchased.
The parts for this repair are only about $1K (both tanks), it's the labor that drives up the repair cost. If I had a two-post lift I would do this repair myself if ever needed but I don't so won't.
