I do not know precisely
Are you speking of upper chamber pressure or lower chamber pressure?
the system fuel pressure is adjusted/defined by the pressure regulator.

Hi just dropping in from Grand Cayman.

Actually there is a trim adjustment beneath that screw. It doesn't affect system pressure. If anything, it affects the leak rate which affects lower chamber pressure.

azhari,
I dont know if your model is exactly this one (a 260E).
here is what is behind the screw (BOSCH part N° 243702007/847)

stevbfl,
do you know what kind of screwdriver/tool is needed for the trim?
