Question: I have a new 2014 Ford F350 6.7L Diesel crew cab with 8ft box and I pull a camper trailer behind my truck and travel from Minneapolis, MN to Lake Gile Flowage up by Hurley, WI  every other weekend my question is do they make a fuel tank that is larger then the 36 Gallon that the truck came with for I don't like paying the price of fuel up in northern Wisconsin? Answer: We offer a Titan fuel tank that would expand your 36 gallon tank to 65 gallons and would fit right in place of your existing tank so no need to make any cosmetic changes to your truck.  Your price is $1437.30 plus tax  and we also can install fuel tank for $275.00. We also have a fuel tank that would mount where your spare tire fits that would hold 30 gallon and would come with Titan's Electronic controller, fuel pump, brushed aluminum fuel door and filler kit they are $1618.20 plus tax and we also can install for $300.00. We also have in the bed tanks available. so give James a call at 1-800-444-0755 and let me help you save money today on fuel.
