Fuel line setup is straight forward: From the gastank to the pump inlet, pump outlet to the carb inlet. Pump pulse line goes to the crankcase. If your new pump is hooked up properly and not working, you may need to gravity feed some gas through it to "wet" the valves inside so they seal and pump properly.
