  1. Disconnect the vacuum hose from the fuel pressure regulator.
  2. Monitor the fuel pressure gauge.
  3. Idle the engine.
  4. Apply 12?14 inches of vacuum to the fuel pressure regulator with a hand-held vacuum pump.
Does the fuel pressure drop the specified value when the vacuum is applied?
21?69 kPa (3?10 psi)
