The larger fuel line (3/8") is the supply line, and connects to the passenger side fuel rail. The smaller fuel line (5/16") is the return line, and connects to the fuel pressure regulator at the back of the drivers side rail. The "3rd" line in the cluster is the EVAP canister purge line, and connects to the metal U-shaped tube about midway back between the drivers side of the intake manifold and the valve cover.

 

hmmm i understand where they hook up top to the fuel rails but i was getting at under the drivers compartment...im assuming the metal lines are differant sizes also???
