There is a problem with your part numbers.
0.438.120.024 is most likely the metering plate number. The FD number is on a plate in the back of the fuel head. A dental mirror will help you see it.
0.438.100.054 WUR is correct for a 930/51 USA engine.

930/51 Fuel System Specifications:
CCP @ 85F = 1.7-2.1 bar
WCP = 2.6-3.0 bar
System = 6.0-6.7 bar

With your current pressures I would anticipate this engine is running AFR rich when cold, within spec at cruise, and lean on boost.
