To continue testing you will need Miller Tool Kit #6872A and #8382.
NOTE: The Fuel Tank must have 1/2 tank of fuel to perform this test.
Perform Evaporative System Pressure Pump Self Test that is specified on the tester
cover.
Warning: Verify the vehicle fuel tank contains at least 3 gallons of fuel.
Attach the DRB III to the vehicle.
Turn the Key On.
At: ENGINE SYSTEM TESTS select: LEAK DETECTION PUMP TEST.
Read instructions and then press ENTER.
At: LEAK DETECTION PUMP TEST select #3 HOLD PSI.
At the vacuum hose going to the LDP, attach and apply a continuous vacuum (i.e. 209
Hg).
Remove Gas Cap.
Install 8382 on the Gas Cap and on the vehicle.
Attach the supply hose from 6872A to 8382.
Attach the power source from the 6872A, clip to Battery(+) and ground clip to
Battery(-).
On the 6872A set the Pressure/Hold Valve to Open and set the Vent Valve to Closed.
Turn the timer on and watch the gauge.
When the gauge pressure reaches 14 in. H2O, turn the Pressure/Hold Valve to
Closed.
Turn the timer off. Note the time and pressure.
