Thanks JWC 3, unfortunately Dennis carpenter does not have the fuel tank I need, i'll keep looking and verify if the F250 and F350 tanks are the same

 

Awesomeness, Thanks so much.

 

See above post. Looks to fit your truck. Follow the link.

 

I see you found it.
I posted late.

 

Ordered!

 

Thanks to Fabman for going all out and posting a link!

 

There is a difference, but you can fix it by drilling a few holes, and making a bracket.
The tank is shaped similar, but not quite the same.
It still fits behind the seat just fine tho

Don't forget to order the new rubber seal between the tank and the cab

 

Parts ordered. Waiting to see how well it runs when installed

 

Let us know.
