The base of my truck is a 86 GMC shortbox with dual saddlebag tanks. I have been contimplating the idea of a blazer or burban tank between the rails instead of the saddlebags. Has anyone done this swap or have pics? About the filler hose would it be possible to run a longer hose from the factory fuel tank doors infroont of the wheels to the tank behind or is that just asking for trouble? Thanks.
