My fitting arrived today, and I affixed it to the end of the hose from the outlet of the hydraulic block (inlet of the loader valve). When I started the tractor there was no pressure, but a lot of fluid came out of the inlet port of the loader valve. I realized I need to place the hydraulic block spool in the vertical position. Then a lot less fluid came out of the inlet port of the loader valve. I'm at a loss. Something's fishy, and I'm less sure that's it's the pump.

Starting at the hydraulic block, this is what I have:
1/C inlet to remote valve power beyond
3/B outlet to loader inlet
4/D tank to loader outlet

At the loader valve:
inlet to outlet of block
outlet to tank with tee 2
power beyond to remote valve inlet

At the remote valve:
Inlet to loader power beyond
Outlet to tank with tee 3 (end 1 into hydraulic block port fitting)
power beyond to hydraulic block inlet port

It's like flow is in reverse. What do you all think now?

I am not sure what you really mean but the hoses and valves seem incorrectly connected.

1=C should be the hose that is coming from the rear remote power beyond port
3=B should be the hose that goes to the loader valve power in port
4=D should be the tank return for both the rear valve and the loader valve. There should be two separate hoses (one from each valve) that could be TEEd together and then connected to the tractor block to return to the sump.

It should be a loop from tractor pump to block to valve power in through valve to power beyond sleeve port to valve power in through valve to power beyond sleeve port then back into tractor block to power the three point hitch and then dump to the sump. Then the two tank lines need to go from the valves to the tractor sump.

Confirm you don’t have a second block on the rear of the tractor
