If everyone did everything the way the GM service manual told us to do it..... we would waste many many hours..... I know some of the guys that write the manuals..... wheeeeeewwwwweeeeeeee........ There is always a better way... well most of the time... Glad I didn't follow the way the manuals told us how to change the rear studs either.... Creativity goes along way...

I've now replaced the canister & valve on 3 G8's (mine and 2 local's) and didn't remove the tank on any of them. The first one I did (my G8) took me 3 hours due to the learning process. I can now do them in about an hour from start to finish. Practice makes perfect

Basically what is the procedure. I have both the po445 & po449 code, which happened strangely right after when while getting gas the pump did not click off, spewing precious fuel on my feet and street. I figure perhaps it over poured into the canister, maybe burn off or evaporate and codes would go away. I tried to clear but the one pops right back on.

Since you know you overfilled the tank, I would think that the hardware is still ok.
In some other post, It was outlined the lengthy process the system must go through to get a reset. Check that out and I would give it more operating time before going down the path of changing parts.
The purge valve selenoid is the only code on now. Where is this valve? On the motor or left side of fuel tank?

this is exactly what caused my issue. You have likely shorted the electrical solenoid valve. I had a post with more detailed directions, as have a few others. Ill see if I can find it.

I know it is not detailed directions, but it will give you a good idea of what is necessary. Basically, lower one side of the cradle and loosen the other to gain access. push/pull/tug to get that damn "not-so-quick-connect" loose. the metal bracket I used a screwdriver to "pry the tang". It pops out, and the new one goes on in reverse. Not too difficult, if you can find the replacement, and access the area to R/R.

Thanks! I think I ordered the wrong part. I ordered the solenoid purge valve which is under the hood. When I tried to look what parts the article said purge valve so I found out were it was and ordered the part. Now I see others are replacing the hard to get to part near the gas tank.
We will see. Also got a tire sensor light now too. Wtf everything at once! I am about to drive 1500 miles back to NJ to get my car inspected and now I throw codes which will fail me!

sorry about the confusion. It should be listed as a canister vent solenoid.
