Detachable Gas Tank - Any ideas?

just remember those quick breaks are not dry. An extra set of couplers with the ends sealed would solve that problem but that's starting to get a little spendy :p
 
For plug use zip tie with mounting hole. Tighten tie to fuel line. attach a brass bolt that you have ground threads off to fit inside line by drilling hole in end of bolt and get some plastic coated steel fishing leader loop line through drillrd hole and though loop in line. then choose your length and using jewelry eyelet make loop in line and insert though hole in zip tie and it is secure. If you choose to use Dutz fasteners you can secure them to bike same way so you won't missplace.
 
There was a post from a guy on one of the motorbike sites that used a soda bottle for a temporary fuel tank and tossed it when empty.
The poster had to travel for a living and he could not find anybody that would ship his motor bike because it had a fuel tank.
To solve this, he devised a stopper that will fit in a soda bottle and accomodate a fuel line and vent line. He simply tosses his fuel tank in the recycling before shipping the bike to his next destination.
 
Soda Bottle Stopper

That might have been me. They work like a charm and no need to sneak your fuel tank onto the bus. Just drink a new one wherever you arrive. Designed for diaphragm carbs, so they're completely sealed...no fumes. If anyone needs one, let me know.

there is really an endless amount of ways to solve this problem. Since there are modifications to the way the tank is functioning,

the first simple stupid cheap way that comes to mind for me is welding or epoxying a nut to the frame of the bike, and then epoxying bolts onto the gas tank where you want to mount it. then its just like screwing on a bottle cap. If you don't want it to be so obvious asthetically you could drill into the frame and mount the nut or bolt inside it.
 
Water bottle gas tank

Heres a nifty one thats saved me the same type of shipping problem.
Get one of those cheap stainless steel water bottles from k mart, gently drill the screw on cap for 1/4 inch steel or copper tubing. One as the gas line the other as a vent and epoxy them in place use small bolts to plug the lines when its not in a standard bottle cage. Quick, cheap and effective, and it looks like a normal water bottle.

BTW if you do carry the "tank" in your backpack be warned that any fuel that just might accidentally leak out will melt holes in the nylon cloth in your pack.

No kidding. I can feature a quick release fuel tank perhaps having merit for needing to store a bike separate from a load of fuel, like for apartment dwellers say, but the thought of slinging a loaded tank in a backpack and getting onto public transit seems fraught with possible unintended consequences.

I always thought the best advantage of a motor assist bicycle was supposed to be if the motor assist fails.......you just pedal home? :D
 
Well, lots else can fail besides the motor.

Motorized bike has two parts - Motor and Bike.

What when the bike part fails? (and I mean FUBAR fail)
