FWIW - I have replaced (two times) the 1" high pressure swivel 90 on the outlet side of my unloader. It developed leaks in the body both times. This is a steel hydraulic fitting. This time I noticed that huge chunks were removed from the inside of the fitting. They had to go downstream and into the pump if/when it unloaded. The steel replacement fitting was $38 and McMaster Carr had the same fitting in 316 stainless steel for $68 so I bought it. You may want to consider using stainless fittings for the sake of pump life.
