Bowl Vent Valve: Testing and Inspection
Vacuum Bowl Vent Valve and Vacuum/Thermostatic Bowl Vent Valve
The Vacuum Vent Valve (E3TE-9G332-AA), Figure 2 should flow air between carburetor port and canister port when no vacuum is applied to vacuum
signal nipple and should not flow air with a vacuum applied at the vacuum signal nipple
The above test also applies to the Vacuum/Thermostatic Vent Valve (E3EE-9G332-AA), Figure 1 when it is at a temperature of 120°F or more. At a
temperature of 90°F or less the valve should not flow air, or be very restrictive to air flow.
