I've been a part of this forum since June and have read multiple posts (and your replies) about this problem. I can't believe it just slipped my mind.
The bike is with the dealer and I get it back Thursday. He is working on fixing yet another infamous bug - the belt chirp.
Unless you do something other than just stick them back on, it's just going to happen again. The real problem comes when the engine is hot, you want to be riding and instead you're waiting for it to cool so you don't fry your arms putting the tubes in place.
My dealer removed the tank, removed the map tubes with their cheesy rubber boots, replaced the tube with a stiff fuel line material (a soft line will collapse under vacuum) and then zip tied them at both ends. 6,000 miles later, still no problems.
If you choose to keep the original tubes and boots, I would super glue AND zip tie them ... but that's just me.
