Fiberglass diesel tanks are not a good idea. It is extremely dificult to
eliminate 100% of the pinholes and diesel will migrate along the fibers much
more easily than water. I would get a quote for new aluminum tanks. I just
received mine from Ezell in Perry FL and could't be happier. Two 42 gallon
tanks with rather complex shapes to use up some awkward shaped space with
anti-syphon fittings and level transducers for $800 including shipping. The
construction was excellent. Just finished bead blasting and priming them so
I am intimately familiar with all the welds.

I have a 43' endeavour with old leaky aluminum tanks that I need to
replace.
Is it possible to build a fuel tank (diesel) that will not deteroiate from
the fuel. Also water...is there a problem with fiberglass water tanks?
Thanks in advance
