The Jetpack Fueller is used to power the Jetpack (not electric) with Fuel. The Jetpack can be anywhere in your inventory, excluding on your back, and hold the Fueller in your hand. Right click on a Tank with Fuel in it and your Jetpack will be instantly refilled, using ~1/4 of a bucket of Fuel.
Note: it cannot be powered with Oil.
