Point taken.? However, I've never had an issue doing this, as I believe
the tank is adequately grounded by both/either contact with the metal
straps and/or the brackets that hold them, and/or by the metal pipe,
which is grounded by several P-clips that are screwed into the
chassis.?? You can always run a small wire from a screw on the sender to
the body somewhere if you're concerned.
Since the car is very effectively electrically isolated by the tires,
the entire car can experience static buildup, and grounding the tank
only disperses it throughout the chassis.? I've been zapped many times
by my BJ8 which has a 'plastic' (mylar?) cover. Removing the cover
creates quite a charge, esp. in low humidity. If I think about it, I
ground myself to the car--usually I make contact with a bare leg to a
bumper--before taking the cover off. The other concern is fueling, where
the flow of fuel can create a charge.? Hopefully, the car gets grounded
by contact with the pump nozzle (note the tank may be isolated by the
rubber sleeve connecting the filler neck and the tank).? Fueling
installations for piston-powered aircraft have a separate ground line
that must be attached before making contact between the nozzle and any
metal on the aircraft (usually, we connected it to the exhaust stack). I
suspect--but don't know for a fact--that this is because the fuel line
and nozzle don't have a ground lead 'built-in.'
