Tank Removal...

Honda uses a quick release that has an extra black rubber piece as an added safeguard, and to keep the fitting clean. Once you know to pull it out first, it's easy. The problem on the CB1100 is that you can barely get a hand in underneath to access it. An extra inch of fuel line would help.

That quick release pictured shows hose barbs that slide onto the hose, and must be clamped in place. I wouldn't trust regular screw-type hose clamps. As peterbaron says, it must withstand high pressures, well above the 55 psi working pressures.
