I am looking for a Fuel Pressure Regulator and I am assuming the whole Fuel Rail with the hard lines/connectors/"O" rings between the Regulator and Rails. Ran into a Fuel Pressure Regulator Failure yesterday with Raw Gas sucked into the Plenum. It is Rare but Happens
I have not figured out how to take a Fuel Pressure Regulator apart but 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.
