I think we're 95% there on this. I've set out a few images to help the orientation of stuff.

This first image is from Rimmer's site showing the stat/housing as it comes.

The next two are Mike's photos with the flow paths

Notice in the photo above how the secondary valve disc appears to have pressure marks where it has seated.

The next is Rimmer's image of the pump swiveled round into the mounted position. We need to understand how the pump works in the block. Are there dividing webs cast into it. I haven't got my mind into this bit. I'm sure it's obvious to some of you.

The next is a combination of stat housing and pump, so we can see how they interface with each other.

This is the pump gasket, showing the port into the block

Here's the gasket roughly in position under the pump

So, the secondary valve closes over the port into the block.
