what SHOULD my fuel pressure be?
Haven’t been able to find a definitive answer regarding fuel pressure.
When I prime the fuel pump initially, the pressure sits at about 75 PSI (5.5 bar). When I start the car it jumps to about 84 psi (6 bar). After I shut the car off, after about 2 hours it drops to 60 PSI, then after 14 hours 45 PSI. Finally after 18 hours it was at 39 PSI.

i was getting around 5-5.5 bar at idle last time I looked. It would drop to about 3.5-3.7 bar at WOT but I can't be sure. I didn't log anything, just quick looks at my phone with BimmerLink.
