ok, so I installed this a year ago and finally got around to finishing the engine. I have this pick up http://www.ebay.com/itm/Milodon-21300-Si...dcb&vxp=mtr

but I had to disconnect the AN fitting to store the engine. So now the pick up was loose in the pan which is attached to the block. I think the side with the holes goes down but I forget? Can someone help me with this. Thanks.
