2. Discharge the fuel system pressure (see PRECAUTION ).

3. Disconnect the fuel inlet hose (fuel tube connector) from the No. 1 fuel pipe.

4. Remove the bolt and disconnect the fuel pressure regulator from the fuel delivery pipe.

5. Connect SST to the No. 1 fuel pipe.

CAUTION:



This test involves high-pressure fuel and electricity.



Take every precaution regarding safe handling of both the
fuel and the electrical parts.



Perform this test in a safe area, and avoid any sparks or
flame.



Do not smoke.

NOTE:

Do not disconnect the No. 2 fuel hose from the fuel pressure
regulator.

CAUTION: Always read the precautions before connecting the fuel

tube connector.
