Here's the deal - I want to carry extra fuel on my 950 but I don't want to spend the $ on the aqualine tanks, or carry around the tour tank since that would kill my top storage box on the back of the bike. So I found these: http://www.funrcboats.com/ProductInfo.aspx?productid=IVTANK1000 But it's only 33oz and that would require ~8 bags for 2 gallons which would be expensive as well as a hassle. So... what are the alternatives? I was thinking a camelback bladder 110oz or MSR Dromedary http://www.msrcorp.com/hydration/dromedary.asp - they come in 10 liters. Will gasoline eat/destroy a camelback or dromedary bladder? Will the gas get contaminated by the polyurethane?
