Hey guys im fairly new to the forums. but ive got a question. I just pulled the motor in my sled to do a top end rebuild, replace all fuel oil lines, and clean things up. well I got the top end rebuilt, carbs cleaned and was about to start reassembling, when I realized I have forgot what the 3 nipples on the bottom of the crankcase are for...what oil/fuel hook up to those nipples and where do they go to. I forgot to label those hook ups and now im stumped 
does anyone have a diagram of fuel and oil line hook ups?. any and all help is greatly appreciated, thanks in advance

Vacume line goes to the pump, left reed cage is a oil line main? If I remeber isn't there one to the water pump gear area? Don't quote me on this, been a while since I have seen under these engines

The one thats under the right reed cage is the one that goes to the oil pump(thats the one I actually figured out). Ill look into one that goes to the water pump when I get home. Thanks for your help!

Assuming all lines push the same amount of oil,right?

Ya im asuming that
there is no "vacum line" on the bottom of the case, the brass port for the fuel pump pulse line is on the top half of the case, goes to the fuel pump.now the lines on the bottom half of the case are the oil feed lines for the oilpump, heres a diagram to show you how they link together, theres 3 nipples on the bottom, only the 1 goes to the oilpump.
