I have the same Craftsman Leaf Blower model CMXGAAH46BT that I purchased at Lowes. I needed the fuel tank repair kit. This post was one of the first to come up in my search so I thought I would register and add the parts list I found for this model to help anyone else with this issue in the future. It took me an entire day to get this and find out where I could get the parts. Lowes told me they can't order this part. I went to several local mower dealers and could not find anything for it. I called Craftsman and after a lot of searching they said it looks like this was made by Husqvarna. So I call Husqvarna and their automated message will send you around until you get to a message that says they no longer support these over the phone and to find a local dealer to assist. I found 2 dealers in my town listed on Husvarna website. Guess who was one of them.....Lowes (who can't get the part) and Tractor Supply. I call Tractor Supply and no dice. I reach out to neighboring cities to dealers and no luck. Finally I am on Husqvarnas website and see the green "Can We Help You" button on the left. I click on it and then other and then chat. I start talking to someone, fully expecting them to have never heard of this leaf blower. To my surprise she knew the part number and not only that but also gave me the whole parts list and some other authorized sellers online, as it was on back order. I was just happy to find out my blower was not completely disposable even if i have to wait a month. I really miss the days of calling and actually talking to someone.
Anyway I am attaching the photos of the parts for anyone in the future that runs into this issue.
