Sorry, meant to say check on the relief pressures. I think you said to set them to the loader relief pressure. The remote valves are preset to 2500 psi.
I found that there is a published port relief setting on the loader lift circuit of 4000 psi. I am not sure if this is significant for my install?
if they are NPT threads, they are designed for a few tightenings. You distort the threads every time you tighten them. Well used NPT treads might leak even with thread dope.
The valve might can handle 4000 psi, but the pump can't, so set the loader relief at about 50 to 100 psi below the pumps max pressure. Then set all relief the same.
