Fuel vapors collect in the charcoal canister until they build up a little pressure, then the purge solenoid allows those fumes to bleed into the engine in a controlled manor.*If you want to, you can eliminate the EVAP system, but you will slowly lose gas to evaporation. If you do this, you do NOT want to plug the line going into the gas tank.... leave it open, it still has to vent pressure. Only plug the port on the intake manifold.
