Looks like I have more time to kill. The manifold is still leaking at the PTC fitting for the LR. It slowed way down when I swapped over to the plastic line but it leaked out over night. I called Airlift this morning and they asked if I was using hard lines and I said yes, why? He said I probably damaged the fitting if I didn’t use the plastic line they provided, but I didn’t void the lifetime warranty or anything which is good especially since nothing is mentioned about hard lines in the instructions. Then he wanted a video of the leak so I did that using soapy water and sent it to him but he said it doesn’t play properly, just send the S/N and shipping address and he’ll send a replacement to swap out. No CC # or anything. Pretty good service. I suppose I might have damaged the fitting, I had a hard time getting the lines to line up and it took a couple tries to bend some of them right so they entered the manifold straight.
