You buy the "compound" separately
I agree, but it was
über trained into me in The Corps in my particular unit to have redundancy in capabilities. Often lower tech, but more robust in durability. I have on the shelf a fuel rated, hand crank pump left over from Y2K (never used NIB) plus the tubing needed for an "emergency withdrawl" of fuel from a ground tank IF the power was off long enough. I also have a kit for turning a 55 gallon oil drum into a wood stove for heating, etc.
I don't know why it took me so long to scratch this particular itch... probably because I have a good supply of flints.
