They were crushed in jack point fail.

There are threads here detailing how to "un-crush" the pipes using compressed air and a torch. Or just buy new replacements from Elephant.

Most all the AC lines are rubber.

Is it safe to assume the external pump isn’t working with crushed pipes and all?

I’m sorry….only one pump in these cars right? The pelican parts rep said they have two oil cooling systems- internal and external. I assumed the external has its own pump.

Those oil lines are for the external oil cooler mounted on the right wheel well. When the thermostat in front of the right rear wheel opens, it sends oil up to the forward cooler.

Ahh thank you. I ordered replacement oil lines. I’m hoping oil flows once they’re attached. Sent from my iPhone using Tapatalk |

Follow up, do you recommend the braided lines for a lower cost alternative (from Elephant racing)

You mean their finned lines?

I suggest that, if it's not been done, you replace both hard lines and the flex lines that connect to the cooler in the fender well. Take your time with the thermostat and the oil cooler threads. Double wrench, use some heat, lubricant etc. so you don't ruin the threads. They can be tight...
If you're really doing it, use this as an opportunity to replace the lines from the oil tank to the thermostat as well, that rubber can get pretty hard after 40 years and crack and such.

As for the finned lines, I tried one and for my street car, didn't prefer them as they fit a bit different. I went with a similarly priced Dansk line.

To further what Johnr said: be ready for a potential tough time with the lines at the oil thermostat in the rear fender. Heat, penetrating oil and patience will definitely be needed. Brute force not at all for it is very easy to destroy the threads of the thermostat. Good luck

I just removed my thermostat...
If you are going to be replacing the hard lines: If you encounter anything more than light resistance when turning the steel nuts that thread onto the aluminum thermostat, cut the nuts off to avoid damaging the aluminum thermo threads- they are soft and easily damaged. Thermostats are $$$$$ I buggered up the threads on one of mine (didn't see the tech write up until after I removed them). The repair kit our host offers probably works fine on the flexible line (engine) side of the thermo, but the two cast thread fittings that face down that attach the hard lines cannot really use the repair kit- it extends the length of the thermo threads out so much that when you attach your hard line to it, the hard line will be poking out below your floor almost an inch more than it should be.
