if you can see air bubbles, I'd say it is not pumping fuel when running. If it is pumping fuel when the key is on and the engine is not running, it really sounds like the pump isn't pumping when the engine is running.

I mean, it could be sucking air, but, the pump should keep positive pressure on the system from the tank all the way to the injection pump. I'm assuming it is like my 6620 titan II. You said it filled a 5 gallon bucket in a few minutes? How about when it is under pressure?
