I am a '92 1500 that comes with the stock 25 gallon fuel tank. I want to know if the 34 gallon fuel tank will fit on my truck. The 25 gallon is: 46 x 12 x 13 1/2 The 34 gallon is: 59 x 14 x 13 1/2 Do you'll think this will fit? Has anyone every done this before. I don't know if my truck bed is 6ft or 8ft long. I am new to this site. I didn't see the appropriate thread to put the question in. Thanks for all your help. I just hit the newbie thread. LOL.
