This 'pump slip' applies only to the 610 pump as far as I know. The 630 unit is somewhat different with the pump not attached at the flange and also incorporates the over-fuel return in the unit.
I've never run it dry, but may have starved it a few times with long wheelies on low fuel... New pump came in, I'm on vacation but I should get it in next week.
Finally got around to replacing the pump, letting the sealant dry right now. Had to ditch the factory pump hose inside the tank, it wouldn't come off of the pump nipple, so I just used regular fuel line and some small clamps. The pump location is nothing like the 610s I've worked on, it's on an extended bracket towards the rear of the tank.
Did you check the fuel hose was submersible type? I just want to warn you that proper submersible fuel hose needs to be used.
