Driver side hpop line to head is leaking a bit. Replace just the fitting or line also? CNC braided lines? RR's jic eaton lines are out of stock, unfortunately.

 

I went with an o ring boss #5 into the engine and a JIC fitting on the end on the stud. Then had the lines built from a double wall 16k psi rated hose at a local hydraulic shop. for the total cost and price of mind might as well do 4 fittings and 2 lines

 

I can't help you on what to do there, I'd have to take it apart and see what the problem is but the lines do go south and if yours have never been replaced, replacing them won't be wasting your money. I made my own line removal tool out of a circular saw wrench as shown in this picture. Don't laugh 'cause the hole ain't square, it works like a dream. I also ground the tip of it sharp so it slides into the fitting easier. That angle on it also helps up on the pump fittings.
