P/S pump leaking from backside

[treetop_73]

I traced the leak somewhere to the back of the unit around where the pressurized line comes in or the return line. Took some time to clean the whole unit, then drive around until it started to leak, crawl under, trace the leak back. But it is not coming from the front where I heard it could be. There is no fluid running down the lines but just down the back and dripping from the bottom. Anyone run into this? I don't want to replace the unit if it is just the line leaking or connection. I don't get much time to work on the truck with the warden and my baby so I want to try to know what to do before I find time so I can get right to it.

Thanks in advance.
