pay attention to what normde2001 wrote. I think he is on the right track.

If the FEL is plumbed in series with 3ph, I would by-pass it to eliminate it as source of blockage, which sounds like what you have.

I have a quick connect hose already made up for when I took the FEL off. I'll try that, but it seems that when it's running unloaded and makes the racket but quiets when you load it sounds like a bushing or something like that.

I will change fluid and clean screen before I replace the pump.

Put a pressure gage in the system so you will know where the pressure is and how much.

It could be a bad bushing or something in the pump but I would try to eliminate as much as possible before blindly digging into/replacing it.
