Fuel Pressure Regulator Reference
Allows the user to choose the proper reference pressure for the fuel pressure regulator. The drop
down menu has the following options:
Manifold Vacuum Reference: This should be selected if the fuel pressure regulator's port is
connected to a vacuum or vacuum/boost source.
Atmospheric Reference: This should be selected if the fuel pressure regulator's port is open to
atmosphere or if a dead end fuel system is used where fuel pressure is constant.
