Our Tech people are starting to require that the metal filler necks of our fuel cells be grounded to the chassis. I'm not exactly a whiz with electrostatics, but that seems counter-intuitive to me, i.e., grounding the filler neck might actually increase the chance of a spark discharge at the filler neck (where there's lots of O2 available). I have read some of the procedures for aircraft fueling, and am curious what (if anything) the SCCA requires. Have there been fires caused by static discharge while fueling formula cars??
