MSR Fuel Bottle Fuel bottles 591 ml - MSR made its Fuel Bottle from a single piece of aluminum and added an air-tight seal so there's less leaking and cracking. The Fuel Bottle works with the threaded pumps on your MSR stove. Holes in the shaft of the bottle cap prevent spills and provide more controlled pouring capabilities. You can store and transport your MSR fuel pump in the Fuel Bottle once the bottle is depressurized.
