This is a post I did on another forum. I installed the Titan underbelly additional capacity diesel tank in my 2008 F350. One of the members here asked about it so I thought I would repost my original thread from the other site.

**************************************
So I finally installed a new replacement underbed additional capacity fuel tank. Titan tanks offers a bolt in replacement 51 USgal to replace the OEM 29 USgal. I always was a little peeved at the small OEM in my 2008 F350 CC SB SRW.
Titan tanks --> http://www.titanfueltanks.com/ They make extra capacity tanks for Ford, Chev, Dodge.
I did it in an afternoon, with breaks for lunch, beers and mow the lawn.

Good to know these are out there.
Thanks for the pictures, too!

I just checked our paperwork - it shows our OEM '08 F350 tank is a 38 gallon.

Yes, OEM long bed is 38 - Titan makes a 67 gal underbed replacement for your long bed truck. Mine is the short box.

Hope this helps.

Take care,
Brian
