MS 400 Twin Fuel System

Does anybody know how the fuel system in a 400 twin works? All the documentation I have only addresses single engine. As I burn down I develop a list to port and haven't figured out why that is occuring.

On our boat there is a crossover line with a cut off valve between the two tanks, it picks up on the aft lower midships corners of the tanks. The genset pulls from, and returns to the port tank. The Stb engine pulls from and returns to the stb tank. The port engine pulls from and returns to the Port tank. The fuel gauge sender is on the stb tank.

Odd that your boat lists to port, ours lists to stb if we put a lot of hours on the genset and pull the port tank down.

I've considered opening the crossover valve but haven't done it.
