Please help me make sense of what's happening to me. What were the symptoms your Z was experiencing? What was the car doing that made you look into the pressure regulator?
Thank you so much!

Ran into a Fuel Pressure Regulator Failure with Raw Gas sucked into the Plenum. It is Rare but Happens
Apparently the air controlled valve/bellows totally failed with raw gas being forced out through the vacuum port and sucked into the Plenum from the Fuel Rails.
Fuel coming out of the Vacuum Port on Fuel Pressure Regulator indicates a failure of the "bellows"/valve. Just hard to find a Fuel Pressure Regulator.
