Hello Ken

EDIT: Claude in your opinion would you ever need to go above 2 bar in pressure? I'm thinking having a gauge that is as close to the max pressure seen will give greater resolution for future adjustments or confirming pressure???[/QUOTE]

Not to need to go above 2 bar.
We ajust pressure at the iddle (engine with starter or running) about 1,1 / 1,2 bar.
Max pressure is an other information to know is pump is correct.
