Just how bad is it??
As far as I know, nobody repops tanks for these. Repairing your original, finding one from a used parts dealer like PlyDo, or getting one from a dry western state salvage yard may be your only choices. Alot of these places advertise in Hemmings Motor News.
www.dvap.com comes to mind. The P15-D24 site may give you some leads also.
