Am i wrong?
I'm not an engineer so I can't answer that.

Any air bubbles being compressed in hydraulic brake lines reduces pressure at the calipers along with making the brake pedal spongy so you're supposed to bleed the brake lines to get them out, maybe there's a relation there?

All bosch k-jetronic/CIS fuel pressure gauge kits have the air purge button just below the gauge for that reason and the instructions say to purge the air out of line going to the gauge before taking pressure readings so it must be important for an accurate reading.
