I built a 30 gallon gasoline tank that worked pretty well. I used polyester
and since then I have heard there is a preference for polyester over epoxy
or vice versa for diesel, but I can't remember which is supposed to work
better for diesel.
I, like Glenn, had some tanks built by EZell. Ezell does a really nice job.
There is also RDS also in Perry FL. ( also a good tank builder)
But if you just want to try a frp tank, build a female mold that will define
the bottom and sides .This can be MDF. Be sure to have big fillets in all
corners because that is where you can be prone to have lamination and
leakage problems.Build the top, a flat sheet, on a release surface. Then fit
the top to the molded part. Also think resin rich, you are not building for
maximum laminate strength but for leakage. Several coats of pure resin on
the inside before you close it up. It is the resin that provides the barrier
for leakage, not the glass.
Anyway it might be a fun thing to try, but.....
