Are the air cleaner and power steering "Star" nuts identical

[Lee Craner]

Are there any differences between these two star nuts?

[Egenolf]

Here the informations of the authenticity manual:

The air cleaner has always a chromed star nut.

The power steering reservoir has either a chromed star nut like the air cleaner or a black square nut or a wing nut (Cadmium).

Thanks, Holger.

All star nuts are the same.

Here is an excerpt from the authenticity manual and a picture of the power steering reservoir nut of 2503 (red circle):

[Pat Marshall]

The Eaton Power Steering Pump is also acceptable for the Mark II - "Although it is generally accepted that only the Vickers brand power steering pump was supplied as original equipment on the Mark II, the Eaton pump may have been installed at the factory on early models. Either product is acceptable for LCOC judging without point deduction or penalty"

The Eaton pump does not have a star, a wing nut or a square nut, it has a screw cap.

I have that pump on my car and it likes to blow the fluid out of the top. Why would it do that? I am constantly filling the reservoir and the fluid always has bubbles in it.
