Feed (-4an). drain (-10an) For feed, tap into oil block which is right above your oil filter, has a spout on it, drill that out and put a fitting on it and connect for feed. For drain you can tap into oil pan or back to timing cover. Hope this helps.

me too, haha. I chose to go to timing cover for drain as it was much easier to get off. You will want to pull whatever you tap so you do not get metal shavings in. Oil pan is a pain to remove so i chose timing cover. However some have tapped on the car without problems but you always run the risk. Oil block is a breeze to get off for feed. The drain is a little more of a pain. Hope this helps Also, steel braided or hydraulic lines seem to be a good choice for the line, some use heater hose as well but not too sure on which is best, but steel braided would get very pricey. I have -4an hyudraulic 2 ply 5 layer for feed and 5/8 heater hose for drain atm, looking to switch to hydraulic however, just need to find some.

a picture's worth a thousand words right? Here ya go.

In this pic you can see the lines off of the turbos, one runs behind trans cooler to the right, other off to right. (I have a scavenge pump due to low turbos and the pump is located over on right side, why they are running over there)


hoses off turbos going to pump


pump


off turbo


off other turbo


feed going to one turbo, and crossing over to other


oil block (tap into that spout for feed)


timing cover tapped for drain


feed again Tee'ing into one turbo and crossing over to other


other turbo's feed


Hope this helps

You can't pull the timing cover with out droping the front of the pan on a LT1 and there's not enough room for a bung on it.
