I would be more inclined to leave alone as Threewheelbonnie says. Just another weak point at some stage. Given that you will fill your tank on the bike more often than your stove, just have a small plastic drink bottle with enough for your stove. Stow it somewhere sensible, when you need it fill up the stove, then next time you refuel fill the bottle up too. You just need to make sure your bottle is the type with a wide neck to make life easy and you can stop start the fuel nozzle at the pump station !
