I was out on a ride today and my main tank signalled it was about to run dry so I flicked the switch for the aux. tank to refill the main tank. Then a few minutes later I spotted a Pilot station with a good price so stopped in and filled the aux. tank.
A couple of miles down the interstate the 2006 GL1800 coughed and burped, jerked a few times - and QUIT. What the heck? I coasted to the emergency lane and turned the key off for a few minutes then started it up again - same thing, coughing, burping and jerking (as in gas-no gas, gas-no gas). Then I noticed the aux tank pump was still on and the fuel gauge needle was on the pin. I turned it off and waited a few minutes while the 18 wheelers zipped by trying to blow me over. Then it started, did the same stuff for a while but finally smoothed out and ran normally.
If anyone knows - is the pump supposed to turn itself off when the aux. tank is empty?
Is the pump designed to turn itself off when the main tank is full if there is still gas in the aux. tank?
Before today I have always had the presence of mind to turn it off manually when one of the red lights on the aux. switch started blinking.
