Fuel system safety items

Morning Bill,
Grab another cup of coffee just because it is Sat. and ya deserve it!!
To quote you= "The spark that burns your ride down is caused when the charge built up in your car attempts to equal the grounded fuel pump's charge (zero)." The clear tube on your filler neck may be conductive and is easy to check with a VOM or volt/ohm/meter. The clear tube does allow you to see gas during a fill up so I like them too but you may also need to apply a ground if not conductive. It should read less than 1 ohm on the meter from end to end.
Them electrons are looking for a difference in potential = ZERO/GROUND so back-wards to what makes sense here. Current flow is bla bla ... its flow follows the path of least resistance so you do not want a resistor in the ground wire as that makes it less attractive to them electrons flowing and trying to blow stuff.
The only hose I have used is from Gates Mfg. and has a wire molded inside the full length. It is labeled with their part # and as FUEL hose. It is also 5 bucks a foot. I have never checked tires to see if conductive but I doubt it. The fact the car is not grounded would keep the static from a gas hose nozzle from discharging when touched to car. If tank and everything is well grounded then if sitting in the car static would be absorbed as there is NO difference of potential. Think of the movies .... a downed power line across hood is safe until somebody that is grounded supplies a path to ground and gets fried like firefighter touching driver.
