it calls for are not listed (or I'm reading it wrong) so, any

recommondations for a fiberglass system? I'm all ears, or in this case
eyes.

If it's a relatively simple shape & you aren't just addicted to resin
fumes, aluminum works great & stands up to just about any fuel. If you
don't have access to a bending brake, most sheet metal shops can do the
bends for you. If flanges are external to the tank volume, you can seal
the joints with 'proseal' & rivet it with 'pulled' rivets.

Gotta agree with Charlie on this one.
Aluminum is way mo betta.

I haven't tried this myself (no guts?) but one of my builders
reported good results using a novel technique.

Flange the end pieces, and make a wrapper skin.
Etch both using the green stuff (phosphate etch from Home Depot?)
Prime with something like Epibond.
Then assemble using PL-1 urethane adhesive (i believe) and pop rivet
the tank together.

Hey, that's why the cal it experimental!

These have been great responses. But what about places to attatch fuel
sending units, gas caps, and drain plugs? How do they attatch and
where? Do you glass in a peice of wood to screw to? or better yet, a
peice of corian that can hold screws but not be affected by wood? What
about support flanges to fiberglass? With enough bouncing around,
screws will rip through fiberglass.
