The fuel pump has an air pulse line running from the metal fuel pump to a port on the engine block, correct? I’m assuming this engine does anyway.
Simply remove the air pulse line from the fuel pump, then have an assistant pump the fuel bulb. If fuel comes out of the pulse fitting on the pump while pumping the fuel bulb, then the pump is NG, has to be rebuilt.
