I'm looking to add an aux tank in the bed under my toolbox, anyone know of any well made ones? Something in the 35 to 45 gallon range would be nice. I'm gonna try to avoid the L-shape ones too...

try www.auxtank.com. I got one with the tool box on top but they have just the tank for under the box as well. When you order it make sure to tell them the year and model because the sending unit is specific to that vehicle so you can run it on your original gauge. PM me or email at helojock@gmail.com for more info if needed. They do come with everything required to set up and the nice thing is it runs directly to your engine not into the main tank like others do. mine is 45 gallons.

 

You can check out These Guys. They sell replacement tanks that fit in the stock location. Looks like the biggest for your year is the 60 gal replacement tank (depending on you truck make). Replace the stock tank with the bigger one, don't lose the spare tire.

 

Another option I think is Transfer Flow:

Aftermarket and OEM Fuel Tank Systems

 

I was thinkin transfer flow to.They have a facility in chico, california about three miles from a relatives house.

 

thanks for all the options guys. looks like these puppies are out of my price range for a little while.
