I have an extra fuel tank in my 2006 long bed truck. I also had a 93 Dodge which had over 275,00 miles. I purchased it from Aero Tank in Ca. I don't have the phone number with me but if you look under Aero Tank.com you will find what you need. I think they also have an extra tank for shortbeds.
They drop the original tank and place the larger tank in the same spot under the bed. They use the same factory original pump and you still fill the same as before. The only difference is the gauge in the cab, it stays on the full mark longer and goes down slower. The cost is about $800. 00. If you go to the factory they can install it in about two to three hours. Make appointment before going. No I am not a salesman for the company just a satisfied customer.
