My 2011 F250 has the 25 gal. Tank and I would like something like a 35 gal. Tank. I don't want a 50 gal. Because I don't haul that long of a distance but 35 would be perfect. Does Ford, Titan or Transfer Flow have something close to this? I would love to just drop in an OEM replacement.

 

I wonder if an OEM 37 gal tank would fit under there. More importantly, if it does, why doesn't FOMOCO put 'em in at the factory?

 

Doesn't the DEF tank take up space beside the fuel tank now that it didn't use to before?

 

If you are going to spend $$$ for a 35 you may as well get the 50.

 

Transfer Flowmakes a 40, they have a variety of sizes..I have a 50 auxillary in the back of my dually and love it...
