Surge tank is used when the fuel tan is not sufficiently baffled. The 1200 tank has partial baffling, but perhaps if you run the tank low it could uncover the pickup tube on cornering. A carburetor has a built in anti-surge tank (the float bowl) but EFI will stop if the flow stops for a moment. Some guys have successfully run EFI with no surge tank, I'd suggest keeping the tank at least 1/4 full at all times.
