1997 Ford F-250 Question: What causes gas to move from one tank to another by itself?

The back tank drains into the front tank while I'm driving and when the front tank gets full it sprays out when I take a turn or hit a bump in the road. Also, the fuel in the front tank rarely runs the truck. Usually when I flip the switch to change tanks it sputters and conks out. It seems to work more often when I start the truck on the front tank.

    Switching valve problem, can block it and just use the rear tank or have it repaired.
