Lycoming systems do not use any return lines. Fuel flow is usualy measured between the throttle body and the spider. The supreme advantage of a return line is that a hot start can be preceded by running the boost pump for a few minutes to purge the system, up to the throttle body, of vapors and hot fuel. This usually makes the hot start easier since it also cooled the cowled fuel delivery system.
