For the Vortech oil feed line, I'm using a 2 1/2 inch nipple to the block and the tee is at the end. At the end of the tee connects the elbow with the oil sending unit. I can't get the elbow in because the AC compressor base is in the way. I tried using a 2 nipple, then I can't turn the tee because it will be hitting engine block. Any advice on how I can get this elbow in? Has anyone here run into this problem?
