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?


I built two nine-gallon gasoline tanks using plywood boxes made
in the right shape, and fiberglassed (with polyester resin) the
insides. The glass/resin came up over all the walls and over the top
lip, which was 3/4" x 3/4" spruce all the way around. The top was
another piece of ply with the inlet, vent and outlet fittings brazed
to steel plates and screwed to it, coated with the glass on the entire
inside surface (including over the steel fitting plates) and laid onto
the still-wet stuff on the lip and screwed down. Never leaked a drop.
Strong, too. This was glass mat I used; cheaper and forms around
corners better. No need for cloth if the wood takes the abuse.
