Default Which a/c lines need changed when gte in a sc400?

I have all of the lines from an sc300 however I can't find any info on just which exact ones need changed.

I thought all of them needed changed however my friend thinks it's just a few so I am at a loss.

All the lines from the firewall to the compressor needs to be changed. This includes the high pressure hoses for the high and low side on the compressor. This is noted in my thread in my signature with pictures. GL.. Let us know if you need more help.

I would also replace all the orings with new ones from the local parts store. Mine had zero leaks and has worked like a champ ever since the AC charge. Are you using piggyback or AEM or Protech or Haltech?

Dang. I thought I'd get away with the ac lines since compressor is in the same location. What are you guys using for power steering lines? I'm guessing sc300 as well? Wish we had sc300 here in Canada would have made things a lot easier

Only the flex lines at the compressor need to be changed. All of the 1997 SC400 AC hardlines can remain in the car.
