Has anyone installed a k5 tank onto a fullsize k10 chassis? The tank I have is from a 78 k5 and my truck is a 78 also. Both current saddle tanks are junk and the newer bed I have is pass. Fuel door I believe. Reason for this is both tanks are bad, and the blazer tank is newer with new sender. I plan on running exhaust stacks through the bed up front and a larger tank would suit me better. Comments appreciated.
