It's been a wile....but I believe that the optimal depth for the pump is 5" to the inlet on it, if you can't go any shorter I would get a hold of some more tubing and try a little lower.

The reason for this is depending on the depth the venturi will pull more or less air into the needle wheel.

One more thing to check is that the inside of the venturi is squeaky clean....if there is any kind of build up what so ever it won't function properly.
