400 miles now since repairing the 449 cel code with the AC Delco part # 214-2149 fix. Thanks agiain. I still got beer money left. One happy camper.

Have 2008 5.3L GMC C1500 with the CEL 449 and 445 codes. Followed the instructions in this thread and it is fixed. Thanks guys, you saved me a bundle. My details are: Went to Advance Auto and ordered the 214-2149 Part for $22.69. They show a 214-2142 for the 08 model that I never tried. It may be a more direct fit/replacement. Don't know and Don't care anymore. The original EVAP vent solenoid was smaller and had two ports. One going to the canistor and one going up next to the tranny with an open end on it. I assume it was trying to get fresh dry air from up there. The 214-2149 part only had the one port. I had to cut the solid plastic hose off of the original as I could not get it off even with soapy water. Only cut a few inches off, just past the nipple of the original assy as to save as much of the original hard plastic hose as possible. You could probably replace the entire hard plastic hose but it is shaped in and "S" and the heater hose would probably fold shut on you, if not at first after time for sure. Installed about 2 or 3 inches of heater hose to connect the original solid plastic hose to the new solenoid. New solenoid slid into the same original bracket and I took the fresh air hose that goes up by tranny and just zip tied it up out of the way. Just in case I need it in the future. The electrical conection was identical and pluged straight in without any modification. As to the location on an 08. Mine was located in the 2B position as per the diragram earlier on in this thread. Just in front of the fuel tank on the left side of the truck. Hope this helps someone else tackle this job. Now that I have money left over for beer I think I will have some. Elbo out.
