Tad: I think it was Yakutat, either that or Cordova, where the rental car company company was absolutely brillant. They had tupperware drawers of all the stuff you can't fly with – bear spray canisters, propane, butane, 6 oz DEET bottles, etc. With a sign saying, "Take what you need, leave behind what you don't."
If you insist on the dragonfly, put the fuel bottle in the sun and wind for a few days. Then put it in the dishwasher. Really. The aklai detergent and hot water remove petroleum really well (that's my day job – cleaning up fuel sites). Disassemble the pump assembly as much as you can and put it in the sun and wind as well. Do that until right before you leave. You'll reduce but not eliminate your risk of seizure by TSA. Occasionally stuff is packaged in matting that has activated carbon in it. That would do wonders to adsorb vapors that will continue to off-gas and help you pass the "sniff test".
Call ahead and find out if someone sells Coleman single-burners that screw onto 1-pound propane cylinders (16 ounces of propane in one pound of steel). Not UL, but they'll have the fuel at any hardware or grocery store.
You could also Priority Mail a package care of yourself to someone in town. Then you'll know it is there before you pack for your flight.
Or come to Kenai and I'll loan you whatever you need – white gas, butane, propane, alky, wood-fired iPhone charger, Mad River Canoe, triple kayak, etc.
Dena is right – the smaller airlines don't check. ERA files from Anchorage to Kenai, Valdez, Cordova, Kodiak and they are outside of TSA. You could fly with propane, white gas, a .44 magmun and pepper spray all in your carry on and people do. But they don't go to Yakutat. Coming in on the State Ferry avoids those issues as well, but I assume you're coming in on Alaska Airlines. Everything on their 737s get TSAed, alas.
Having a night in town at a B&B (not a hotel) gives you a leg up. Locals you can talk to who can probably loan you whatever you need in the way of stoves, fuel, etc. Yakatut has a nice one on the water that also offers fishing charters.
