Works like it should easy fix for a common issue on gm trucks
Fits great, easy to install once you remove spare tire. Bought it for a 2007 Cadillac Escalade ESV. Kept getting an annoying Po446-po449 and had nozzle kept clicking off when getting gas. This fixed everything no more check engine light, no more clicking off at the pump and gained 3MPG. Absolutely worth it.

Worked as it should
Worked as it should. Install wasn't the hardest and it's an OE part so it should last long enough. Now I can pump my gas in a 3rd of the time.

Fits 2010 Suburban, get wiring adapter!!!
This does fit a 2010 Chevy Suburban and you will need the recommended wiring harness adapter. The install took about 30 minutes start to finish. All you need is 13mm socket wrench, cutters for the zip ties, and maybe a pocket screwdriver for the plastic connector on the tube that connects to the vapor canister. The part arrived on a genuine GM box with label and for perfectly in the location.

Did not eliminate our problem.
Product was fine; installed simple enough, but unfortunately these EVAP systems can be clogged in other areas, preventing you from getting much gas in before the filler neck backs up and shuts off the nozzle because the gas tank vent line is blocked "somewhere". VERY irritating. We're still trying to figure out where it's clogged. Product itself looked great, new GM part. You always need to start with this part. Sometimes it's the sole problem, sometimes not. Hope it works for you.

Factory OEM. Fit perfect and fixed my P0449 Code.
I have a 2009 Chevy Tahoe that issued a P0449 Code. I bought this and the ACDelco 19257603 plug adapter. This was very easy to change and took me about 1hr. It took 30 min to get the stupid spare tire off. It was stuck and I had to use a long screw driver to release the safety lock. This canister comes with a new steel bracket and all new hoses. I absolutely needed the ACDELCO 19257603 Adapter since this canister has the updated electrical plug. This is an updated canister. The hoses are shaped a bit different than the factory original. I had the route the stiff hose under the charcoal box then up instead of above it and then down. This was a non-issue but just wanted to make a note of it. The flexible breather hose fit fine and came with zip ties to fasten it to the frame. Also note that this will not fit the old steel bracket. The canister comes with a new bracket and I had to use it to get the canister to sit in the correct position. The old bracket will causes the canister to be installed incorrectly which will pinch the stiff pipe. The new bracket worked perfect and all the pipes fit as they should - use a 13mm wrench to remove the single bolt holding it on the frame.. Overall this was a very easy change and the only tools I needed was a 13mm wrench, flat screw driver, and wire cutters to cut the old zip ties, and a $10 code reader to reset the code.

Perfect fit, installs in an hour (after the spare tire is out). Cleared my CEL issue. It looks WAY harder than it is.
My 2009 GMC Yukon XL Denali had a check engine light, and the code indicated a bad vapor pump. Since the part is relatively inexpensive, and because it includes all the hoses, I bought this to replace the old one. Installation was a little rough because the rear undercarriage of an SUV with 175k miles is a dirty place. If you do this job, make sure you have safety classes. And a way to take a selfie after you're done, so that your wife will think you worked really hard. Watch which hose you're disconnecting from the canister. I wrestled with the wrong hose for a while. The correct hose came off easily. Do a youtube search for a good tutorial. I watched Brian Eslick from How to Automotive - he has a great one, although its for a 2007. DON'T cut off the zip ties that it comes with. They have a double-head, so they can be used to connect the vapor inlet tube to the filler neck. I discovered that my old hose that runs up next to the filler neck had worn through. The vapor pump probably sucked in all kinds of dirt through that, killing it. This new design has a protective cover over the tube, so that shouldn't be a problem in the future. The whole thing took about an hour, after I got the spare tire off and not including fighting with the wrong tube on the vapor canister. This is absolutely a DIY, in the driveway, after work and before dark kind of job. Just watch the video first, and hype up the job to your significant other that it will be REALLY difficult. So they appreciate it more. And just like that, the CEL light was gone.

Does not fit Suburban 2010. Connector is different and the hose to the canister is bent differently. I had to buy additional wiring pigtail and to swap the hose from the old valve to make it fit.

Now i can fuel the car peacefully!! P0446 check engine code fixed !!!
The GM agency asked for 6000 dhs to fix the problem i had that when i stop at a gas station , the fuel pump keeps stopping when fueling which was super annoying and it takes so much time to fill a full tank, watched a couple of YouTube videos on how to fix this issue and bought this amazing product which came from the USA within 5 days with normal shipping, the installation took me 1 hr and i had no previous mechanical experience, very easy to install and the problem was solved and no more check engine light, very happy and satisfied
