What size is the fuel return line ? 1/4" ? Is the vapor seperator line 5/16" ? In the first picture I posted is the vapor seperator mounted in the trunk. The line at the top of the picture is towards the front of the car and the line at the bottom is towards the trunk of the car. Is the front vent line the one that goes to the engine compartment ? Anyone have pics of this routing besides the ones that are already posted ? This is for '71 with the 4 vent lines coming out of the front of the tank. Thanks
