No, the line attached to the jet goes back to the fuel line from the tank. Volatized pressure between the carb and fuel pump simply goes through the jet, bypasses the pump and goes back to another T in the fuel line from the tank.
Basically, it allows the volatized pressure buildup to bypass the pump's check valves and go back into the tank instead of pushing the needle off the seat and flooding the carb.
