volvo cpr pressure

[Tourettes Tony]

hi all, im still in the process of changing over to volvo set up, one problem i have is over fueling but before i start sending things off for rebuilds, can anyone tell me the control pressure cold to hot on a volvo cpr, im assuming it starts around 1 bar then as it warms up goes up to about 4 1/2 bar correct me if im wrong, im only seeing 40 psi when warm then it stops increasing , also fuel pump pressure is around 70psi so its not that help TT
