1. Connect a hose to the EVAP two-way valve (A), then connect a T-fitting (B), a vacuum gauge, and a vacuum pump/gauge, 0-30 inHg, to the hose as shown.

2. Apply vacuum slowly and continuously while watching the gauge. The valve should open below 1.33 kPa (0.393 inHg, 10.0 mmHg).

If the vacuum hold below 1.33 kPa (0.393 inHg, 10.0 mmHg), go to step 3.
If the vacuum doesn't hold, replace the EVAP two way valve.

3. Move the vacuum pump from the vacuum fitting to the pressure fitting (A) as shown.

4. Slowly pressurize the vapor line while watching the gauge. The valve should open above 5.07 kPa (1.497 inHg, 38.0 mmHg).

If the pressure hold below 5.07 kPa (1.497 inHg, 38.0 mmHg), the valve is OK.
If the pressure doesn't hold, replace the EVAP two way valve.
