I have also grounded my caddy directly to the gas hose handle before pumping. That should be a low resistance connection to ground and dissipate the charge faster. Do you think that is a good choice for grounding?

I need to update some software first... but I should snap a pic of the safety stickers on the pump islands here. I was reading one recently at a station, and noted the relevant clause/subclause legislation #. But, turns out our province seems to have privatized the handling of said legislation's documentation - either that or it is so buried on the provincial site that it is not readily found. (I can only find it For Sale so far - Go Public Safety !).
The relevant clause said that a drum/caddy should be electrically bonded to the vehicle, or trailer that it is on. Sounds reasonable, at a minimum.
I know a little bit about grounding in general, but not gas pumps in particular (from a hard-core engineering standpoint). The "rubber" fuel hose
could be made to be fairly conductive electrically, but I don't know for sure if it is or isn't.
My inclination would be to connect a ground as far away from the fuel openings (hose end, tank fill port) as possible, to reduce the chance of a spark near vapour. The fuel pump chassis should be well grounded itself, that would be my first choice.
As I think V1R mentioned, electrically grounding is standard practice for airplanes, before doing anything else. This is well understood in aviation, not so much at 7/11. If you clip onto the hose handle, likely nobody will notice - if you clip onto the pump itself, the kid inside might think you are "hacking" the gas pump !
I need to find some better general purpose documentation on fueling up road vehicles, esp. with aux. tanks.
