914-6 oil tank question - too many orifices? Options

[moparrob]

For the longest time I was having difficulty trying to picture where the oil lines go to and from on a 914-6 conversion - but I think I have most of the issues figured out.

A lot of the problem has to do with the tank I bought. It has 'extra' holes and fittings that most other tanks I have seen did not have.

Here is a pic:

I finally figured out that fitting 'C' is the AN -12 return line which is usually a hard pipe from the engine which attaches to a flex line to this port.

Similarly, I figured that fitting 'D' is the supply line that goes to the oil cooler, which in my case is AN -16 on both ends.

The confusion arises out of fittings 'A' and 'B'. Most tanks I see do not have these fittings. Also, my car was only pre-drilled (by the PO) for fittings C,D, the filler, the vent and the filter only. I don't have extra holes for these fittings.

So, do I need these fittings A and B? What do they do?

If I don't need them, how do I get rid of them? Do I have to braze the holes shut? Or is it easier to just drill the two requisite holes in the engine compartment and use plugs on those fittings?

Last question, does anyone know the size and thread of those fittings?

Thanks in advance for your help.

I wonder if they are pipe thread (taper) so that I could use a plug? Otherwise, if it is a straight thread I guess it would seal on the top surface with an aluminum washer?

Or perhaps I could unscrew those fittings and find threaded caps?

I repeat. They're metric fittings, NOT pipe thread. Just get a couple of plugs, a couple of copper gaskets, and be done with it.
