It's illegal to tender for carry any HazMat in your luggage. Signage is all over the place at check-in counters etc. If TSA finds it in your checked bags they'll play hell with you.

Purchase new "unused" fuel bottles to carry in your bag. Old "used" ones can still have a trace (smell) of old fuel. TSA will frown on that too.

Get whatever fuel you need at destination. Plan on either shipping the empty fuel bottles back to yourself via UPS/FedEx or just giving them away before you get back on the plane for the trip home.

Follow this advise, and you'll be fine and avoid trouble with the TSA (Thousands Standing Around).
