5. Press the ON/OFF switch to turn on the SST and make sure the left display reads 0.0.
6. Turn the control valve on the tester to the FILL position.
7. Verify the left display reading is within 13.9 to 14.0 in of water.
If not, adjust the pressure using the regulator knob located on the right side of the tester.
8. Turn the control valve to TEST position and press the START switch.
9. After the 2-min countdown (left display) is completed, the right display shows the total pressure
loss for that period. A 0.5 in of water loss is acceptable on the self-test.
If the loss is more than 0.5 in of water, do one or more self-test. If the failed test repeats,
check for leak using the ultrasonic leak detector (part of SST).
2. Press the RESET switch to set the left display reading to 0.0.
3. Connect the fuel cap receiver assembly (part of SST ) to the manifold assembly and fuel-filler cap from
the vehicle.
If the fuel-filler cap is not a genuine part, replace it.
4. Turn the control valve to the FILL position.
5. Wait (maximum 20 s ) until the left display reads 13.9 to 14.0 in of water.
If the reading is slightly below the specification, adjust it using the regulator knob.
If the reading is far below, the fuel-filler cap has leak. Replace it.
6. Turn the control valve to the TEST position and press the START switch.
7. After the 2-min countdown (left display) is completed, check the test result (the failed/passed light on the
tester).
If the green light turns on, the fuel-filler cap is normal.
If the red light turns on, the fuel-filler cap has leakage. Replace it.
