This was accompanied by a warning on the combination instrument which said "Fuel Pump Failure".
I was in the middle of nowhere at the time so I had to try to restart the bike which I did and it ran perfectly. I rode a mile down the road, stopped the bike and opened the gas cap again, no pressure. I rode all the way home and carefully opened the gas cap, (outside and away from my house) and no pressure this time either.
On older bikes, I've seen a slight vacuum form in the gas tank if the air bleed to the tank was obstructed but never seen or heard of any condition which could put the tank under such great pressure. Anyone seen this or have any idea what it might have been?
