full or empty the fuel tank is, and how long it takes to completely fill and pressurize the evaporative
emissions system hoses.
8. If the gauge and the flow meter do not settle to a measurable level after
2-3 min
, then refer to the
appropriate service article to verify that the cut or vent valve is properly closed.
9. Verify the pressure gauge and flow meter reading to determine if there is an evaporative emissions leak:
NO EVAPORATIVE LEAK:
The flow meter registers "zero flow" and the pressure gauge returns to the pre-set pressure of
356
mm {14 in}
of water (H2O).
EVAPORATIVE LEAK:
The pressure does not return to the preset level of
356 mm {14 in}
of water (H2O) when measuring
the flow. See "SETTING LEAK STANDARD FOR TESTING" (.020 to .040 inch H2O) of the
Evaporative Emissions Tester operators manual (134-01067).
NOTE:
Turn the control valve to the HOLD position then disconnect the SST.
