Technically.... it'* not an HVAC purge .. it'* vacuum for the HVAC actuators (the vacuum ones) so they move. Technically it feeds a canister to keep pressure even when at WOT etc and vacuum on either motor may be low.
A supercharged picture won't do the same for him.
Todd. Dealer is your best way to go. Bring in the vin and they should be able to provide them to you. As for the air pump, it only feeds into the exhaust. Doesn't have any lines that are under say 3/4" in diameter.
You'll have the booster line going to the plenum, the HVAC line feeding off an elbow on the top of the boosters connection port. Then the evap, it come up from the tank and over to the valve, then from the valve to the throttle body. FYI, you could replace it with regular black lines.. no need for the special ones etc. Just give them extra length where they need to bend.
