Where did you route the return line? On my 69' there is a hole in the rear frame for the supply line to go through where it runs over the axle.

I'm running all -10 from the cell to the regulator and -8 for the return. I was going to run -10 for the return also, but Aeromotive said no need. The regulator after the carb seemed a bit strange, but the fuel sytem has been rock solid and I like the clean look it provides. Both my fuel lines are simply run between the frame connector and the rocker panel and come up to a pair of bulkheads coming into the trunk. Very simple and clean .

The regulator after the carb is a great system. I have a lot of D Track alky users that run that type of system. It keeps a good solid slug of no aireated (SP?) fuel to the needle and seats.
