ressure all depends on circumstances. For example, if the unloader valve is in unload position, the pump output is being dumped back into the sump via a backpressure (low pressure} valve, with nothing going to the lift cylinder. Study & understand the flow circuits. If you take measures to block off any pump flow other that via overpressure relief, you should see 2000-2200PSI

Correct. Moving the lift or draft
levers does not affect pressure in any
way. Plug in lift cover where valve
would go has very little flow & no
pressure. My question is Would it be
valve etc. & can it be fixed through side
plate like 8n etc.
