Has anyone changed out a fuel tank on a 2011 or newer 6.7. I would like to put a stock 37.5 gal tank in, what all do i need to do. I looked at buying a after market tank but dont want to spend the $$$. About the put the dpf delete on. do that help with space

 

I have replaced my stock 37.5 gal tank in my 2015 CC LB 6.7L with a Titan 65 gal tank. Most of the aftermarket tanks are designed to fit stock location and use straps that bolt to the stock locations. Installing a tank not designed to fit the stock location might cause more problems than worth in the long run. Be safe and bite the bullet to do one time big spend to get a tank designed to fit and avoid a catastrophe down the road if your "hope-it-fits tank" fails.
