Static Sparking
The SB requires draining the tanks. Falling fuel generates a static charge. Has anyone mentioned that you can set your airplane on fire by draining fuel without considering static electricity?
We all use plastic gas cans, so do yourself a favor. Obtain a large STEEL funnel. Attach three stranded copper wires at two points with pop rivets or screws/nuts. The first is attached to the inside of the small end of the funnel. Make it about 18" long and bare the last 6". This one goes inside the gas can you are filling to submerge in the fuel. The other two wires attach to the upper lip of the funnel and get alligator clips on the ends. One is maybe 2 feet long, the other as much as 6 or 8 feet. The first clips to a good airframe ground. The other clips to an earth ground, which can be a well-buried steel tiedown if nothing else.
