2 To continue testing you will need Miller Tools #6872A (Evap System Pressure Pump)
and #8382 (Gas Cap Tester/Adapter).
WARNING: The test equipment is designed to be used to pressurize the
vehicles Evaporative System only. Using the equipment in a manner for
which it was not designed could be harmful.
WARNING: Keep lighted cigarettes, sparks, flames, and other ignition
sources away from the test area to prevent the ignition of explosive gases.
Keep the test area well ventilated.
NOTE: The fuel tank should have between 20% and 80% of fuel tank capacity
to properly test the Evap system.
Attach the power red source clip of Miller Tool #6872A to Battery (+) and the black
ground clip to Battery (-).
Perform the Evaporative System Pressure Pump self test that is specified on the
tester cover.
Remove gas cap and install Miller Tool #8382 on vehicle. Install gas cap to Miller Tool
#8382. Attach the pressure supply hose from Miller Tool #6872A to the fitting on
#8382.
Disconnect the vacuum supply hose at the Leak Detection Pump. Connect and apply
a continuous vacuum supply (i.e. 209Hg) to the Leak Detection Pump. A vacuum
pump such as an A/C recovery unit works well.
Turn the ignition on.
With the DRBIIItin System Tests, select Leak Detect Pump Test. Read instructions
and then press Enter. Select: #3 - HOLD PSI.
On Miller Tool #6872A, set the Pressure/Hold switch to Open and set the Vent switch
to Closed. Turn the pump timer On and watch the gauge.
NOTE: If the pressure does not build up, there is obviously a large leak in
the system and the presence of strong fuel odor may be present. A visual
inspection should find a leak of substantial size.
When the gauge pressure reaches 149H2O, turn the Pressure/Hold Valve to Closed.
Turn the pump timer off. Note the time and pressure. After 10 sec of stabilization
time.
Did the pressure drop more than 69H2O in 2 minutes?All
