<p>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.</p>
<p>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.' <br>

<p>Get some reinforced rubber stock--places like Orchard
Supply (maybe Lowe's, HD, etc.) sell it--and put a
couple strips front to back to level the tank and keep
it off the boot pan.</p>
<p>BTW, if the tank hold-down straps have evenly-spaced
holes they're for copper rivets to hold a thick
canvas-like padding. You don't want the straps
rubbing against the tank either (substitute rubber if
you like).</p>
