Pressure Regulator Inspection

WARNING: This page is about a different car, the 2004 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • Due to the adoption of the mechanical returnless fuel system, the pressure regulator cannot be inspected separately.
  1. Perform "FUEL LINE PRESSURE INSPECTION". (See FUEL LINE PRESSURE INSPECTION .)
