return line?
is it possible for the return lines to drain into the tank that is not switched on? I filled up my back tank and now it's below half and the front tank is full after 3 days and maybe 50 miles. So, I'm thinking when I run on the back tank the return lines are draining into the front tank. Is that possible? and if it is, how do I fix it? I had this happen a few weeks back and thought I was just being a tool and had forgotten which tank I had it on, but here we go again.

When the FSV switches it should go ZZIIPP at that point the fuel level contacts and redirection of the valve should be complete. The completed operation is indicated by the new fuel level. IF the fuel is going to the wrong tank then the valve is fubar. Do not discount a bad connector or wires so check them.
