Trying to retro fit AC on Zane's 71. Compressor is from 2001 van that had a 5.7 vortec. At some point 25 years ago, the system was replaced. There is no high side port. Probably have more questions than I know yet.
New drier has label says flow with arrow. Which way does the flow go? From condenser or to condenser?
How much gas does the system need? I read where it depends on pressure in system when running. Can I get this from the port near the firewall (low side I think)?
How much oil do I put in?
