The problem is typical in multiple tank setups. Fuel flows to the path of least resistance. Also over time the tank levels are affected by the boats balance and fuel will flow to the down side.
One solution is a day tank the engines draw fuel from and that tank is filled as necessary from the main tanks. That's how I have done it in all my boats. Another is to slightly close the valve on the tank losing fuel. And adjust as necessary. Eventually you will find a close spot, but it will change depending on the fuel level. A globe valve works best for regulating flow. Or try permanently shifting some weight to the port side.
