I've had the tips of the impeller vanes wear off and combined with the set which the vanes had taken the pump was unable to generate enough force to both suck and blow unless I reved the engine. This condition didn't cause any perceivable problems until I was attempting to winterize and the level in the jug just wouldn't go down.
If you haven't replaced the impeller lately. Replace the impeller and get back to us.
