Testing Hydro Pump on G1000

How can a guy test the output pressure of the pump? Iv installed a pressure gauge according to manual and all I can get outta it is around 300 to 400 PSI. Manual calls for 1650 to 1750 i believe. Iv adjusted the regulator valve screw to no avail. I went through the valve block and found a few broken springs for the Aux. Valves replaced them and according to book everything should be synced. I didnt need to adjust anything. IT Manual mentions nothing of the hydro pump. All it says is if the pressure is lower than specified the master valve is not synced correctly. It does tell you how to rebuild the pump but no way of testing it. It is a Vickers piston type pump. Also when I drained the oil in the system it was pretty dirty with what looks like brass dust.

Local semi-retired farmer has 2 G1000 tractors. One has closed center hydraulics, the other one does not. I have not seen either tractor in 2 years but I think both have Vickers pumps. Does your tractor have the open or closed center system?
 
We have a G-900 and a Vista both have the same Vickers pump you show in the picture and both are closed center. We also have two more Vistas with the smaller pumps and they are both open center systems. I thought all that used the large Vickers were closed center but I may be mistaken. One of mine needs work too, it won't pump at all so I need to pull it off and see what's wrong too.
 
According to Welters it's an open system. But from what little info I have found the Vickers pumps are not very reliable compared to the Webster.
