Hi Matt,
I think you may have your CP1 & CP3 upside down.
As a rule CP1 has a supply pressure of 2.5 bar ish
CP3 may have a pre supply (normally electric) of about 0.5 of a bar but normally it has a mechanical gear pump attached to the back of the high pressure pump (running off the same driveshaft) that feeds the ZME (IMV) internally.
