Liquid Vapor Separator: Description and Operation
With Standard Evaporative Emissions
Fuel vapor in the fuel tank is vented to the evaporative emissions canister (EVAP canister) through the evaporative emission valve and has these
characteristics:
-
Mounted in a rubber grommet at a central location in the upper surface of the fuel tank.
-
A vapor space between the fuel level and the fuel tank upper surface is combined with a small orifice and float shut off valve in the evaporative
emission valve to prevent liquid fuel from passing to the evaporative emissions canister.
-
The vapor space also allows for expansion of the fuel.
