Gas tank/ lines issue
I have a 2009 c6 corvette, so a little bit ago i hit a cinder block on the road and was unavoidable. I took the car in for a diagnosis because i noticed a strong gas smell and found out the cinder block ended up hitting my gas tank. The tank is now a little loose and has a decent size dent, im not sure what it broke on the top but it now has a leak. I called a specialist in my area; he told me whenever people try to drop these gas tanks to fix a part or something the lines break and they have to replace those aswell. He told me, due to gm filing for bankruptcy and not paying their vendors they dont really make the gas lines no more. Now he has to try to get an aftermarket company to make these lines for him. This is my daily so, if anyone else has had this issue or know how to fix it please let me know.

If this specialist says that the fuel lines break he probably isn’t much of a “specialist” and he will probably break them if he works on your car…if your tank is cracked and leaking you just replace it…don’t know what else to tell you…that’s how you fix it.

I replaced the fuel pump in my C6 and did all the work myself. It was a PIA but I was careful and did not destroy the internal plastic lines in the tank. There are some plastic barbs that hold the lines in place in the tank and it is almost unavoidable not to break one or two of them. But the lines can just be held in place with some simple small zip ties.

The right-angle outlet on the outside of the fuel pump assembly itself is also crack-prone. If yours is busted you'll need a new fuel pump. I gather from recent reports that the pumps are currently hard to find.
As for not paying vendors, the C6 was in production for 4 years after GM emerged from bankruptcy. I think parts are unavailable just because parts for old cars always become unavailable.
With all that said, yours may well come apart without too much hassle. It's not like you have a choice. I would find somebody to drop the tanks carefully and evaluate what's broken.

First were are you located? Someone may know i place to take it.
Second when my fuel elbow at top broke (know defect) the Chevy house had no parts and could not find any.
Went with my corvette specialist here in Austin and they got me fixed up for 2600.00. They double checked everything that could go wrong and only needed the fuel pump and wiring harness( due to the gas leak ruining all the seals)

One thing to add.
Since the torque tube, transmission, diff, rear subframe, etc. will be out of the car, this will make removing the gas tank much easier as who ever does the work will have nothing but room. And because of this, it should make things much easier to be careful and not screw something up.
When I did my fuel pump, I did the work while everything was in the car and I had very little room to see. Had to do most of the work mainly by feel. And I was still able not to break anything.
