Hey guys I recently got the P0455 code on 2007 Tahoe and in the process of chasing down an EVAP leak. Purchased a new OEM gas cap, Purge valve solenoid and vent solenoid with hoses and filtered vent.
Questions:
1. The stock vent solenoid had the vent hose routed up near the filler neck and on the end of the hose was what appeared to be a cap. Strange. The new (I assume updated) vent system has the rectangular open box with coarse foam filter media. Is there some ECM software update that must be done when changing to the updated vent system?
2. The firewall side hose that connects to the purge solenoid in the engine bay had a old brittle white clip that broke when I went to remove the hose. Can anyone confirm that the Dorman 800-032 is the correct replacement part? They're expensive and I don't want to order a set and find out that they won't work.
Thanks in advance!
