I've heard there is no after-market replacement for these tanks. And the 2.0 tanks don't have the opening needed for the fuel pump.

BradMPH or one of the other members mentioned some sort of paint you can coat the interior of the tank with...some sort of enamel or epoxy. MY problem is the top fittings for the fuel lines...which I repaired with Bondo and concrete caulking, but some day, the pump will need replacing, and I don't think the tank will survive the operation.

I'd put feelers out to the junk yards, there in Kansas, and see if you can't find a decent used one.
