86 Phazer Rebuild

I am putting the engine back in my Phazer and am hooking up the oil lines. I have run into a problem with my memory and where all the oil lines connect and run. I have most of them figured out. I am drawing a blank with one of the tubes. I had one that comes out of the back lower part of the crankcase. I can't figure out where it attaches. As I have it now, I have two tubes going to the oil tank and then two tubes going to each carburetor/reeds. I am very green on this stuff, but thought I'd try the rebuild and see if I could do it. Thanks for any help,
ERic
