----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]---- The refueling ground wire is to stop one particular spark...the one that can occur otherwise when the nozzle contacts the filler. Planes (and some boats) are particularly vulnerable because the puddle of gas and fumes is right there....not at the other end of a filler neck, like in cars. So it's easy to go kaboom. The 'ground' wire isn't really a 'ground' wire so much as a wire that is connected to the fuel pump (which connects to the nozzle by way of a wire that is internal to the hose) to make SURE that a spark doesn't jump when you start to fuel.
Also, fuel going through the rubber line creates static, and this keeps everything in agreement. Remember this if you find yourself without a ground wire (happens too often). Ground the nozzle to the plane AWAY from the filler neck before approaching the filler with it!
