Need a gas tank. 1982 Tarpon 19 dual console

[Wrestling Coach]

My tank has deteriorated and dumped gas into the bilge. The problem is age and corrosion. I know these tanks are not sitting on shelves any longer so I am looking for a poly/plastic replacement tank close to the dimensions/capacity and plumbing of my old one. Anyone have a source for such marine tanks?

Thanks In Advance---Dennis

I called rds aluminum in fl about a tank for mine and they had the plans on file, they were the oem maker of my tank. I wound up not needing a tank anyway.
