J had a new bottom welded to my fuel tank last Fall....same issue as
yours...pin hole leaks. I cut some old battens for the tank to rest on.
The tank is held down by two (2) metal straps, approx. 1 1/2 inches
wide, several feet long with holes in the straps to put your screws
and/or nuts/bolts. The back of the strap(s) is bolted to the aft
bulkhead, comes up over the back of the tank and down the front and
bolted to the front stringer. The tank can't move side to side either
as it fits into its wooden deck it sits on.

A few weeks ago I discovered a diesel leak from the bottom of the tank
– the tank had 2 areas of pitting and one was sufficiently deep to
start leaking and warrant replacing the tank. I now have the new AL
tank and have a couple of questions about installing it:
The old tank was not strapped down and was resting directly on the
ends of 2 stringers and the hull, surrounded on the sides [fairly
tightly] by plywood. This allowed the tank to shift slightly, more or
less in place, which wore on the two end points of the stringers, and
that is where corrosion developed and the leak occurred. A while back
someone (Rick Brass (?) who is probably a little busy with Florence at
the moment) recommended glassing in old battens under the tank to
reduce the opportunity for moisture to collect and corrosion to
occur. Last week Joe mentioned he used Dri-Dek. Is there a consensus
on how to best support a fuel tank?
The constant shifting of the tank was a contributing factor for the
leak. How do people tie down / strap AL diesel tanks? There is not
much that looks overly solid to which I can screw in hold downs, like
those that come with this from Defender:

And what to people use for straps? Would this Sceptre product be an
acceptable way to restrain the tank?
Any suggestions?
TIA,
Brian
