A pulse type fuel pump uses 3 hoses. One from the tank to the pump. One from the pump to the carb. And one from the pump to the engine crankcase. It uses the vacuum/pressure pulse to to run the pump. Now on Onan engines you may not see the third hose from the pump to the crankcase because it is hidden behind the pump going though the engine cover. Makes removing and installing the engine cover REAL fun.
