Ford 223 six

I have a "63" Ford 223 straight six, anybody know anything about the oiler tubes that go to the rocker arm ***embly? I have one (the front one) that is just rattling around in the engine case, and one that has a fitting on the end of the tube. Is one the oiler and the other the return? Somthin don't seem right.
Can anyone fill me in?

 

One is supply to the rocker shaft and the other is return. One tube has an oring that seats into the oil gallery (supply) the other one dumps oil back to the pan (return - rattles around).

 

Thanks Man! That's what I wanted to know, I just put the ***embly back together yesterday and was hoping for the best, I feel better now.
