Wouldn't an old coffee thermos (32 ounce) or an old aluminum water bottle (20 ounce) work to carry extra gas in, or would the sloshing create too much pressure? I have one of each and was thinking about painting them red and putting GAS in big letters on them so no one would try to take a sip

and strap them on the back

Thermos , if it is glass.might break but the aluminum water bottle would work just fine. Try to mount it where it will be shaded from the sun as gasoline can expand like mad

The thermos is double walled stainless. Sorry I should have specified.

If you could rig some sort of a vent in the cap that would not allow fuel to spill out it may work. I would keep an eye on the cap and seal as most caps are plastic and may not stand up gasoline.

1 quart MSR Fuel bottles fit in that storage tube just right

 

[FortPayne]

MSR are about $20 shipped. Dollar tree has aluminum water bottles, well, for $1. Let us know how it works out- I might have to go spend $1

 

[FortPayne]

Double post.

Yeah, the MSR bottles are pretty popular. Their stoves ain't bad, either. The issue I've heard about with regular metal drinking containers is venting, and the rubber seal breaking down.



For like two days, I used a magnetic parts tray as a gas cap and the fumes ate up the rubber base that covered the magnet in that amount of time.

The MSR has a pressure relief cap

I assume the only problem with a regular aluminum water bottle is the cap right? Would a cork work or would the pressure just blow it out? Any other ideas?

A cork is doable, maybe. It would be a definite Burt Munro moment.

Great movie. Saw it again last week. The oranges off my tree aren't quite as sweet since my dog died.

Liquid gas does not expand much with increase in temp (has a low coeffecient of expansion) - it's the vapors that expand, and possibly the liquid vaporizing into gas. If the can were full and the cap on tight, there would be very little pressure in it and I do not think it would blow off or be a hazard. I don't think a filled SS water bottle is dangerous except if it leaked. The bottle itself will certainly not burst.

Fill the bottle up with gas, turn it over for a few days and see if it leaks or if the rubber or neoprene gasket deteriorates. I bet it'll be fine but the only way to tell would be to test it.



What kind of pressure release cap is on the MSR bottle? If it had something like that and it was lying on it's side or upside down, then pressure would squirt gas out the vent.

I am going to try a couple of bottles upside down for a few days and see what happens. I have been reading about the MSR bottles and in the description says they have an air tight seal to prevent air from degrading the fuel. I think they are using a normal O ring so if the water bottle O ring or seal does not work I can replase it with a common O ring.

Went to town and got 2 of the ss water bottles. I thought they had a plug but nope, its a threaded cap. I even found 1 that had a larger mouth than all the rest (1 1/2" or so). They are 25oz. each. If they work out $2 sure beats $20.

They are aluminum not ss, any chane of pressure explosion or anything?

 

[TW-Brian]

Put some gas in them, lay them on their side (outside) for a few days, and cross your fingers that the caps don't turn into mush.



Good luck and let us know your results.

Buy a gallon of Coleman fuel, dump it in your cage, and keep the can. Fill to within 1/4-inch of the top flat top, squeeze to force the level up to the top of the threads, tighten the cap. Best leakproof gas can I've ever had, and more efficient use of space than round bottles.

 

[Ssokzon]

I've been wondering the same thing regarding water bottles used for gas...but I noticed that Coleman is selling their fuel in smaller round bottles in Walmart( I think it's a quart? )as well as in gallon cans, so maybe emptying one of them to reuse would be better (the cap may not degrade??)

 

[qwerty]

Coleman fuel is gasoline. Anything that will hold Coleman fuel will also hold gasoline. However, if ethanol is involved, you're on your own.

 

[FortPayne]

The bottles are great for riders without racks or with minimal storage.



Sat it upside down overnight and today. The seal that comes with it has become stretchier if thats a word and must be careful to seat it properly, but no gas leaked out. Other than the extra elasticity the seal seams fine, still holding shape and firm.



Qwerty I like the idea of the coleman fuel can. Any idea if that fuel can will fit inside a regular sized ammo box? Just added an ammo box pannier this afternoon.
