A Little More.....
Thanks, greenman! I thought that was the case, but I realized that I wasn't quite as explanatory as I should have been.
I was planning on verifying the electrical wiring to the vent solenoid, and change the vent solenoid if needed. My question was really to confirm the location and part number of the vent solenoid.
Some of the online GM catalogs I have seen, including the drawing/diagram excerpts posted here, show a rectangular shape unit near the vapor canister. This is labeled by GM on some of the stuff I can find as a purge solenoid and not a vent solenoid. The drawings on sites such as GMpartsdirect.com only list a purge solenoid. Without any service manuals, I was hoping to glean some info from those, like yourself, that have replaced this.
Based on this, I have been able to locate two sets of part numbers (Rock Auto is an easy one to look at). My problem is that I just wanted to verify that the vent valve (round/cylindrical part) was what is mounted above/next to the gas tank before I tear apart anything.
