Closing a progressive line #2 fuel can with screw cap
Place the cap back on the neck of the fuel can.
Close the fuel can shut by screwing the cap clockwise.
Screw the cap until you feel resistance. Then turn the cap an additional 1/6 of a turn. Do not tighten the cap too much, as it may be difficult to unscrew.
Whenever tilted, make sure that the fuel can is airtight.
