I'll tell ya what I know & it isn't much. I also received the recall & called my FL facility. Many will be lucky with only an inspection & others will need a whole new length of hose installed. I scheduled a trip next week to find out which group I'm in. They did let me know they already have one hose on (critical back order) so the part won't be available just yet regardless.
