On the fuel pump.the line from tank enters the port on the left (horizontal). Where does the bottom port (vertical) go? Briggs & Strotton,Model 402707 Type 1212-01 Code94100454. THangs Don

Hi,
I gather this is a separate pump, not one built into the carb. The outer nipple is the vacuum, back vertical is inlet(from tank) and the right horizontal is outlet(to carb.)
Peace,
