Title: Suburban rear heater lines.
Post by: 90_suburban on July 13, 2019, 09:36:31 pm

What have people done for replacement lines. I don’t really want to run rubber lines down the frame. I still have the factory metal lines but they are really rusty would like to replace them while I have the body off and cleaning the frame up.

I’m in the beginning stages of swapping a 12 valve Cummins into the frame.

Run copper or nickel copper lines
