Even when I put the smaller head on the pump it still did the same thing. I have not seen a bypass valve for this gauge. Chad

The tipoff is the pump producing "an incredible amount of water." The output of the pump for most gauge 1 locos needs to be only a dribble when you disconnect the bypass line and allow the pump to discharge onto the ground. Axle pumps have proved satisfactory in everything from 0 gauge on up, especially when combined with a bypass valve which permits fine adjustment.
