there are three hoses attached to the evap can and when i changed the can out for a new one and reattached the hoses i noticed the fresh air hose was hanging underneath the car and not attached to anything. Is that supposed to be connected to anything besides the canister or does it just do nothing? Cause im not getting any vacuum in the can to open the purge valve attached to the other line on the can coming from the fuel tank and the purge line from the motor to the can does have vacuum going through it so i know its not anything with the vac lines. both purge valve and canister are brand new. if i hold my finger for awhile over the other end of the fresh air inlet tube, then i feel vacuum in the evap can which in turn is suppose to happen to open the valve.
