Okay, so I have a '99 K2500, 4 door that has the 25ish gallon fuel tank. I have been looking at trying to put a 42 gallon Suburban tank where the spare tire sits(I dont need the spare because I have 35s anyway) and removing the stock fuel tank. I have the 7.4 so I only get maybe 10 MPG city and 8 when towing. Has anyone ever done this? Is it possible?? Any knowledge or advice is greatly appreciated.
