Slick 60's

anybody know of any underbed plastic tanks that would work with a bed fill?

I parted out a 79 f150 4x4 that had dual tanks. The front tank was plastic. I kept it and plan on trying to use it.

Tanks Inc has some plastic ones that look like they'd work. You just have to find one with the capacity and dimensions you want.

Custom Classic Trucks mag did a tech article a few issues back using a "universal" tank (steel though...). perhaps this may give you some leads and ideas as a "between the frame rails" install is pretty generic.

perhaps a swap meet alternate: my 66 longbed came with fiberglass auxiliaries from an outfit out of Fort Worth, TX that has since gone out of business. they were ahead of the rear tires, outboard of the chassis rails. about 10 gals each with fill necks accessible through the wheel wells. pretty sweet install strategy as an alternate idea for keeping the spare tire between the rails, out back. my longbed tanks would definitely not work on your shortbed though - takes up the entire space.

good luck!
