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 don't want to be the debbie downer in this thread
but my 2cents.

in 26 years of 914 ownership, modifying, and racing
I have never once seen anyone looking for a sporto tank
I agree they are rare, but there is also zero demand because so few (practically none) cars were ever built needing them

I do remember about 8-10 years back when the factory sold off remaining inventory of sporto tanks. They were cheaper than the standard tanks because there was a push to dump old inventory that had no demand.

I'm not trying to be a buzz kill
but you may find that it brings no more money than a used standard tank
you may want to just use it.
I find that when my car is on jackstands too long, I sometimes have to take a step back and just start finishing things. May not always be the way I wanted them to be absolutely detailed... but still getting a running and driving car can take small sacrafices to the perfect car that isn't driveable.

I'm very proud of the quality of my race car project. I had to make sacrifices to get it done in a tight time frame. Its not perfect but I've had 6 years of fun with it now as a runner, versus still trying to get it perfect and have it still be on jack stands

not trying to slam anyone
just my opinion
your tank is a good tank
it will work
you may sell it easily (I hope)
or you may not be able to sell it and focus a lot of time and energy to be right back where you are.
