OK already! I've seen enough conjecture on static spark prevention....
Sorry to be so bold, but I may have some final words regarding this
important issue...When the CAF foundation evaluated N111EU we discussed
this topic. They did considerable research previously on this matter and
determined that if you just simply use a wetted towel to wipe around the
fill neck prior to filling and keep it at the fill neck area during filling
(like setting your gas can on the towel), the static charge potential is
eliminated. To be safer, I also ran a ground wire from the fill neck to the
battery ground, engine (includes exhaust), and engine mount and swing arm
frame to accommodate the ground wire provided at the fuel pump or fuel
truck. I carry a ground wire with appropriate alligator clips in N111EU to
connect to unknown dispensing sources for greater assurance.
Hope this helps!
