Would probably be my choice.

Tek-Tank will make welded HDPE water and holding tanks but their line of
fuel tanks is very limited. Fuel tanks have to be cross linked
polyethylene and you can't weld XLPE. It has to be rotomolded so you
are stuck with the tooling cost.

I know this will not solve your problem, but on the twenty footer I
will be building, I planned areas such as fuel storage areas to use
common size readily available marine fuel tanks. Easily replaceable in
any marine store.
I don't need to carry as much as you, but I have two 6 gallon tanks
(mains) in the rear of the boat, with a third stored in the bow. I can
just plug them in as I need them. Just thought I would note that to
anyone else is in my situation and watching this thread.
