I've got a little p/s leak and am not 100% sure if it's leaking from where I think it is. It looks like it's coming from the return line on the gear box. There is some play in the tubing that goes through the connector. The truck recently was bullet-proofed, so they separated the cab. I'm wondering if there is supposed to be an o-ring on that line or some other piece that keeps it in line and keeps it from leaking. I was going to just replace the line, but I don't want to spend the $80 if it's just an o-ring or something similar that I can replace.
