Default A/C lines?

Good morning! Just bought my first Corvette and absolutely love it!

The previous owner removed some a/c lines and the condenser. Can someone please steer me in the right direction and tell me what lines to order and or part numbers?
Thanks- Brandon

Okay, I think I figured it out. The only line I don’t know what it goes to is the middle picture. It runs behind the motor and have no idea what it is?!

Someone removed the AIR system when they installed the headers

....actually, it looks like they left at least some portion of the AIR system in place based on the second picture.

Update your profile with model/year info. All C5's are not the same.
I wish you luck, I think your in for a bit of a wild ride.


Here is basic components in the A.I.R. system.

Thanks! I don’t care about the AIR system. I just want to get my air conditioning working. It has actually been really hot here in Michigan! I’ll probably get it working by the time it snows! Lol

Forum members seem to generally be pleased with Rockauto.com. I have only made a few purchases from them but have been pleased with the part selection and prices. Their site lets you shop by part name. Alternatively, go to a site like gmpartsdirect and find the parts diagram with all the GM part numbers. Or do both approaches.

IF everything was removed, by memory, you will need:
Suction/Discharge hose assembly which connects from the A/D to the compressor and from the compressor to the Condenser inlet
Liquid line from the Condenser to the Evaporator
Evaporator outlet to the A/D inlet

Other parts you will need:
Accumulator/Dehydrator (A/D)
Orifice tube
O-rings and seal washers for the compressor
Flush solution for the evaporator and anything else that had been open to the atmosphere
If the compressor has been left unsealed, it may be corroded internally
