Not sure if you have a permanent solution to the loose line yet, but I did this job last summer and damaged one of the quick connect retainer clips on the tip of one fuel line without knowing it and it wouldn't snapback in. Called a mobile mechanic to help get the lines off and pull the tank a second time and he discovered the broken clip. Quick trip to parts store to get a multi-pack of clips of various sizes was all it took.

 

There is a company called speaker works that may have a fix for your speaker. Low tech garage had a video fixing that same speaker where the paper cone had deteriorated material connecting outer part to speaker base. Real cheap and they may have solution to your problem. Used his vid to gain access to hoses on evap unit on top of tank then cut them between tube making unit independent of tank and thus easier to remove and replace hoses easier. My speaker has same problems his had so will probably repair it before replacing everything
