By crackie, there ARE three lines....quite clearly Fuel send....Fuel return and Evaporative containment~

one of them goes to the charcoal canister (thru containment valve)...both the others are connected to the fuel rail...the SEND will be routed through the fuel pressure regulator~ return just goes back to the tank....for 'nuff pressure of the injectors under the highest of demands.....gotta have 'nuff fuel...okay~?
