Notice the brass or copper tips on the vent lines. I guess to prevent sparks? See how the separator is positioned, all vent lines enter the bottom where it can drain back and the actual vent nipple where the vent line attaches is up top.
Actually I believe the 1/4" return was clamped to the other 2 lines from the factory and not in the bolted on clamps, they have these s hooks that hold the line to the other lines. This is the only place I put all three in on e clamp on this car, they don't really fit.
