1. Two outlets at the shutoff valve:
- The first outlet connects to the carburetor float chamber.
- The second outlet connects to the petcock vacuum port to create a vacuum seal.
2. Two outlets on the tank:
- The first outlet serves as the primary fuel supply line. It connects to the shutoff valve inlet located near the frame backbone to supply fuel to the carburetor.
- The second outlet serves as the reserve fuel supply line. It connects to the shutoff valve inlet located on the opposite side of the shutoff valve assembly. This allows you to access additional fuel in case the main fuel supply runs out.
Here's a step-by-step explanation:
Step 1: Start with the two outlets on the fuel tank.
- Connect one outlet to the primary fuel shutoff valve inlet (usually located on the left-hand side of the frame).
- Connect the other outlet to the reserve fuel shutoff valve inlet (usually located on the right-hand side of the frame).
Step 2: Connect the remaining outlets.
- From the primary fuel shutoff valve, run the fuel line to the inlet on the carburetor float chamber.
- From the reserve fuel shutoff valve, run the fuel line to the vacuum connection port located on the petcock.
This routing ensures a properly functioning fuel supply system for your 1973 Yamaha RD350.
