You should run a ground wire from the filler cap ring to the frame with any cell. Think about this, your plastic cell is an insulator for your filler cap ring, therefore you need the ground. On your aluminum cell, did you put the rubber gaskets between the filler cap rings and the aluminum to seal it up? They are an automatic insulator for the filler cap ring. Yes it may touch the metal, or yea the bolts may touch the metal some where, but not enough to make a "good ground". Put a ground wire on it and you know it is grounded and there fore no arc flash threat.

That's my $1.250.



The thing with ANY plastic tank is as you pour in
fuel either by a can or at the pump you are building
static electricity and if you touch it with anything
weather it be your hand or a metal you will discharge
it and it does create a spark and if its in the right
area and the F/A ratio is close enough it will
light it up.. being that I worked in the fuel lab
we had to measure the static build up from MULTIPLE
sources... filling the tank, people sliding in and out
of the car seat and other things... so we had to have
a way to discharge this before the people could fill
the tank... doors on the filler tube area is one
easy way but we didnt like to have it discharged in
that area due to the cap vent... thats PART of the reason
you are suppose to take fuel cans out of the car
to fill them... you would ground them out when you
pick them up to place back in the car.... and we are
only talking millivolts here
