Getting a bit fed up with my Vmax's limited fuel range, which is made worse by the way I ride it
So im thinking of getting a custom Fuel tank to put somewhere on the back, actually thinking about having one made to fit inside a civi luggage box, about 4 or 5 gallon tank.
Can anyone tell me the advantages and disadvantages of doing in the follow way..
Having the Aux tank mounted high to allow gravity to work for me, Aux tank will feed into the main tank through the overflow outlet opening with a tap to turn on and off the Aux fuel, so I can close the tap when I want to fuel up both tanks.
Heres what I dont know.
Will the main tanks fuel supply still function correctly if the overflow pipe is effectively blocked off, my understanding is a standard fuel cap has a breather hole, but the above method will require me to make sure the tanks fuel cap is completely air tight as the aux tank will force the fuel level to rise to the top.
Or if I just close the main tank fuel cap off completely would the aux tanks cap breather be ok, and maybe have a larger diameter pipe going from the aux to the main tank meaning I only have to fill up into the aux tank
not really wanting to go down the route of having another fuel pump for the Aux tank..
Any advice would be appreciated.
