Hello. I have 2 oil lines to my oil pan in my 1988 omc 3.0 What is the line in the back of the pan for? It has a compression nut on it? I cut the line and took the thing out. Is that for the oil pump? Any help is greatly appreciated.

Not sure on yours, but my older OMC had one that was designed to hook a pump to. Rather than drain oil in the bilge, I would pump oil outta' that one.
