Jack -
This area is very prone to holding moisture... corroding the tank and
boot floor. With an aluminum tank, it will only be worse with
galvanic corrosion.
I would put small rectangles of dense neoprene stripping under the
tank (1/8" / 3mm thick neoprene is fine) to lift the tank a little bit
off the boot floor. This will allow moisture to escape and prevent
corrosion. It will also allow some cushion for the tank when driving
around, with no cushion the interface between tank and boot floor will
be prone to wear... and corrosion. I would also make sure the tank
and boot floor is given a good strong paint job.
Set up this way, this should last forever.
For the tank hole I would put some neoprene strips in there to start,
and then once the tank is in use your foam to seal up the rest.
Best Regards,
Alan
