Title: Factory OEM. Fit perfect and fixed my P0449 Code.
Review: 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.

Title: Great product – fits perfectly – solve p0442 code
Review: I bought this to solve the p0442 code I was getting on my Chevy Avalanche 5.3 FLEX. I first change the gas cap that can cause this code which is cheaper and easier. You want to rule the gas cap out first. In my case it did not fix the problem so I had to purchase this Vent Valve which is a common problem with this vehicle. It is relatively easy to change. The most difficult part is to lower and remove the spare tire from the truck, and dealing with all the dirt that fall in your face as you work under the truck. Wear goggles and\or hose off the dirt first . If you have not done this type of thing before, pay attention to the vacuum hose connector. You have to push in the plastic clip to remove or else you will have a hard time taking the old one off and brute force will break or crack the cannister nipple and put you in deeper trouble. Look closely at the new one first to see how it works and then take off the old one – it should slip off easy. The new bracket is shaped differently but still connect to the original bolt location.One more thing… You will need the Jumper Wire Harness – ACDelco 19257603 – BUY IT! You will thank me later.

Title: 2007 Chevrolet Avalanche – CEL Code P0455 Large Leak
Review: Determined to resolve the CEL Code P0455 Large Leak, that plagues me through the summer months & inhibits remote start.Having thrown the engine purge valve & new gas cap at her without success, I resolved to tackle the other likely culprits. Thus I purchased the following:GM Genuine Parts 22963841 Vapor CanisterGM Genuine Parts 23481275 Vapor Canister Vent Valve(Spare Vent Valve Solenoid Jumper Wiring Harness Connector 19257603)A simple job that took a fair while longer than it should have, as the spare wheel that wouldn’t lower so after spraying with liberal amounts of WD40 & waiting it finally dropped to the ground.Thus I finally resumed the quest to track down the root cause of my P0455 Large & went in to replace the vent valve.Can you see the problem boys & girls in the pictures?Yes the hose between charcoal canister & vent valve was totally gone (except for the right angled hose connector that remained attached to the canister).I replaced the canister vent valve, very quickly, using the new pigtail connector, though the older unit had the same adaptor cable & I kept the vapor canister for another day or just in case of future problems.It worked out cheaper for me to buy the genuine parts & get them shipped to Montana for my pickup, than it did to source clone parts &\or get a garage to perform the repair in Canada.Total time best part of 4 hours for what should have been a very easy job (Allowing for a half dead hand), 90 minutes maximum would be a safe number, bonus points I can lower my spare tire & have resolved to check that each Spring & Fall from hence.

Title: Does not work in 2009 Tahoe
Review: I always try to buy GM parts for easy installation and reliability. However this one was a fail. The hose routing would have worked, even though the formed lines were different. But the electrical connector was totally different. So I returned the product.

Review: 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
