I have been debating on doing something similar. I don't like the idea of cutting into the stock fuel system because of warranty issues. So, has any done this and had warranty problems?

I was instead thinking of adding a secondary fuel tank, somewhere between 25-50 gallons. I would never add fuel (from filling station) to the stock tank, but instead fill the secondary tank. I would use two good fuel filters and a lift pump to fill the stock tank from the secondary tank (i.e. clean fuel). This would keep the stock fuel system stock, give me clean fuel, plus extra capacity.

What do you guys think?

Hoot,

I could probably put in a fuel gauge for the second tank and a switch in the cab for the transfer pump. Shouldn't be too much hassle. Most of us that tow would love the extra fuel capacity. The stock 26 gallon tank is not much!
