Where could I find a fuel line diagram for a 92 Yamaha XJ600 Seca II?

For the fuel pump portion you can go here - http://www.bikebandit.com/houseofmotorcycles/1992-yamaha-motorcycle-xj600sd-carburetor/o/m8199sch138373

Two hoses come from the intake area under the carburetors - the small hose on the left side (facing front) which is directly under #1 intake goes to the Fuel Petcock vacuum input. The hose under #2 intake goes to the Fuel Pump - vacuum intake (marked with P). The left side of the fuel pump is the input for fuel - the right side is the output for the fuel pump - the hose goes up to the small T input between carburetor 2 and 3. The input for the fuel pump has an inline fuel filter and that runs up to the Fuel Petcock fuel outlet.
