This is how I have solved this problem in the past. Not on the 690 tank but, on the 950 tank and a snowmobile tank. Might add.....make sure you don't push in while it is hot. Always spin it while pulling at the same time if possible. Be sure to clean both surfaces very well prior to epoxy. To reinsert grease up a bolt to hold onto, the grease is so any extra epoxy doesn't lock it in too, I always use liberal amount of anti-seize on all insert type bolts now days.
