I'm not sure how well the fuel is cooled in the fz6 tank (but I like to think it is at least some amount). I suspect heat from not having enough fuel to cool the pump, and, condensation from always running around with an empty tank (at this time of year temp between night and day fluctuates big) are 2 of the hardest \"normal\" occurances in an automotive type fuel system.
For those reasons I try to keep my tank reasonably \"full.... ish\".
