Ok - I know - old topic... I replaced the vent valve, and the purge valve... Purge valve was easy, but the vent valve was a PITA (on 2003 prior vehicles). I got it all installed, but the kit didn't come with the required 5/8" hose to re-route the vent intake. WHY??? You'd think if you ordered the new kit, it would come with the necessary hoses rather than having to go to a auto parts store to get the required heater hose! It is 8:30 PM on Sunday night, and there is no place open to get that hose. Sorry for the rant, but this bugs me...
