Maximum pressure is 210 Bar, which is just over 3000 psi.

What would cause this machine to run as if it is loading up. Even during the simplest operations. It has a new pump and all new o-rings in the valve body, this is also why the pump was changed.

Can be engine with fuel issue, if the pressures are not high when it loads up. Have you replaced fuel filter and checked the flow of fuel to the injection pump?
Customer: replied 5 months ago.
I replace fuel and air filter believing it was a hp issue to begin with. How would I check to see if I have the correct fuel flow to the injection pump? I did try a different electric fuel pump also.
Expert:  Curtis B. replied 5 months ago.
Take fuel line to the electric fuel pump into another fule container, bypassing the fuel tank and lines to the transfer pump, for test.
