GMParts 22963841 Vapor Canister

Factory OEM is the only way to go, Item works great and fitment is perfect, canister and lines.

received it right on time and was glad to see that if it exactly like it was supposed to. There was no problems with installation as I read with some of the offbrands. Thank you for a great product at a great price.

Good quality, fits perfectly on Yukon XL.

Again I was skeptical buying a part for truck on Amazon. But it was the perfect it. And cleared my codes. I was surprised on the difference in cost. I purchased this for a 2005 Avalanche LS

Does not fit 2011 yukon denali!! It's too big for the bracket. Need part 15220023

This is an exact match to the original part on my 2006 Suburban. It was easy to install once you get the hoses off. Old unit was saturated and weighed 9 ozs. more than the new unit. This was the cause of my gas tank filling slow and tripping the gas nozzle off like the tank was full. It also solved the P0446 code causing my check engine light to come on.

Many owners of GM vehicles know about the slow filling of their gas tanks due to problems with the fuel vapor evaporative system. This problem had gotten progressively worse in recent years so when I put my Avalanche in the shop for several maintenance issues, I requested the mechanic to check & replace, if necessary, the evap solenoid which he did. However, the slow fueling problem got worse; much worse. Following recommendations by several on YouTube, I disconnected the vent hose from the fuel tank to bypass the charcoal canister and drove to a filling station and the problem went away. The fuel tank was now able to vent the pressure coming from introducing fresh fuel. I ordered this item and saved ~$65 versus the local auto parts stores and probably at least that amount if I had returned to the repair shop I originally took my truck to, not including the labor. As I'm in my late 60s, I rarely do any auto repair work any more. It's just easier to take it to a shop and be done with it. And it's not an especially easy job to perform, especially when you're working on your back on a creeper. Doing this with your vehicle elevated on a lift would be much easier. If you attempt this replacement, be sure to watch the videos that are available, especially those specific to your vehicle. These evap systems are all basically the same but accessing the different parts varies. If you like a challenge, go for it.

I purchased an after-market canister, figuring all the GM/AC/Delco stuff is made in China so it is likely to be the same manufacturer anyways. Well, it wasn't. The nipple for the purge valve on the after-market was 9.7mm wide, and the line won't stretch. The original GM part and this replacement which is GM have a 9.2mm nipple. Checked with calipers.
