Stock Fuel pressure on a 2000?
I just want someone to verify this for me. What should the idling fuel pressure be for a 2000 XJ, both with the vacuum source connected and disconnected? I've been running my 2000 injectors at around 42 psi at idle with the vacuum source connected. Is that too high?

1997-2001 4.0L 49psi +/- 5psi is normal.

Connected. I don't think vacuum has any effect on the fuel pressure.
