Looking for a Manual illustrating the proper fuel line & wiring for a B&S 256412-1153-E1?

I have an old Homelite LR5500 generator with an 11HP Briggs and Stratton engine that I'm reconditioning to sell. However, it has a 3 pole switch and wiring which I'm not sure how to properly address it, and the fuel line is not a direct connect to the carburetor but through some form of fuel pump assembly. I've downloaded the engine specific owners and parts manuals, but they do not illustrate the proper wiring or how the fuel lines properly link to the pump then carburetor.
 
Maybe I should add the switch is two-way with 3 poles. White, Red, Black. White is split and it appear maybe one end of the white goes to the Coil and the other is hanging loose. Red looks like it is grounded to the engine, and black I'm not sure. I'm not sure how to attach pictures here, but I will if I figure it out.
