Im trying to figure out which one is the return fuel line. (Looking on the drivers side intake manifold) The top one comes from behind the motor and T's off and goes to each fuel rail. The bottom one goes from behind the motor and goes to some kind of solenoid or something that is sitting on the driverside fuel rail. (not sure what exactly it is). Im trying to put the Fuel Management Unit into the return line, but not sure which one it is. Thanks for any response.

Yep, small line is return. Keep us updated.
