oil pump lines?

[hopper16]

i have a 88 exciter 570 L/C, and am trying to figure out where 2 of the 4 lines go. I have the 2 small ones "T" off into the main gas line, but not sure where the other 2 bigger lines come from or goto, this sled was in kinda tough shape, and things where not how things should be when I got it.

I think the 2 bigger ones go to the oil tank and into a T fitting in it but I can not tell from the book I have. I will check a different book I have and let you know.

Here is what I found.

Hope it helps.
