Broken gas nozzle overflowed tank.
After owning and riding bikes for over 35 years, this finally happens.
On the third tank of gas ever pumped into the tank, the nozzle stuck on when filling the tank. As the fuel got to the top of the tank and I realized the thing wouldn't shut off, I whipped the still-flowing nozzle away from the bike and shut off the pump. I stopped it before it actually flowed over the top of the tank but I still sprayed gas across the bike and fairing and gas did go into the overflow and presumably into the carbon canister. And believe me, the poor employees at the station got an ear-full from me about the broken nozzle.
I have ridden several hundred miles since this and had no problems with fuel delivery or any running issues. However, I notice now when the bike is parked in the sun, black colored gas drips from a hose under the bike and the gas cap hisses. It occurred to me today that the black gas is most likely due to the overflow.
I hadn't really planned on yanking the carbon can on this bike but will if it might damage the engine to leave it as is. I certainly won't put out the cash to replace the carbon can if it could be an issue.
So, finally the question:
Is there potential for polluted gas to flow back into the tank and be run through the engine?
Are there any other potential issues from gas in the canister or shall I just keep running it as long as no symptoms emerge?
