My 2010 Fury now has its auxiliary fuel system in place. Custom metal working, custom fuel line and fuel system modifications, and custom electronic control system to govern how long the fuel pump is actuated when I press the button on my handle bars.
The great thing is I have another 3.5 gallons which effectively doubles my range between fill ups. I just wait for the low fuel indicator light to come on, press the button, and 1.5 gallons are transferred from the auxiliary tank to the primary up front.
