Vacuum

[TO123]

(I'm driving an L200, 2005, 2.5 Turbo Deisel, K74)
Can anybody out there quantify the 'normal/healthy' vacuum levels that I should expect (if I were to tee a gauge into the system) at any locations between the vacuum pump and lets say at the check-valve before the solenoids, at the accumulator on the chassis rail, and at the 4WD/diff lock actuator ?
(I have vacuum, it swaps as it should as the solenoids change between 2 & 4WD. The manual / fault finding advice describes 'weak' vacuum. My vacuum feels weak throughout - trouble is I don't know what normal feels like.
Thanks

under the intercooler you will find a rubber cap onto a nipple,  take that off,  put some hose on it and touch it on your tongue,   that,  is good vacuum.


as is the  pipe going down to the turbo when engine is at idle
