Fuel Tank Rust

[z250kid]

I just was painting my frame when i droped my skid plates to revel rust and some putty slapped on the tank. The sealer so its tacky and starting seap threw it. Its a 96 f350 4x4 regular cab, and 8 foot bed. My question is what size tank is this? Its steel. i want to replace it with a plastic but theres, two different options from rock auto, either 18 or 19 gallons.

what one do i need?

[z250kid]

sorry its the rear tank. after the axle

[95 Powerstroker]

i think the rear is a 18 gallon I THINK.

[z250kid]

the plastic one is better then the galvized steel right?
it wont rust due to sand/water

The rear is 19 IIRC on the 97. IIRC. Here is some info that doesn't really answer the question for sure. But I think both my tanks are 19 gallons.

Aft of Axle Tank 18.2 gal (US)

Midship Tank 4 x 4 w/E4OD trans and 3378 mm (133 in) wheelbase 22.0 gal (US)

All others 19.0 gal (US)
