Hi just a quick one, i have a fuel pressure gauge on the fuel rail from the Fpr.

With the car idling with handbrake on in neutral...

If i rev the car 'slightly' manually via the throttle body butterfly to ~3k rpm should the fuel pressure rise quickly then drop down to its set pressure ie move the TB butterfly then let go.

I thought they weren't supposed to move? - my gut feeling is it should as I'm letting air in when opening the TB plate. At the moment is jumps up slightly then if i let go it drops back down again, its just a read the FPR is 'static'.

Thanks
