Well I've got my mits on a FSM and the vanes do indeed go in as shown above.

The bit that goes around the vanes also needs to be in the correct way.
There is an arrow cast into this bit to show the direction of rotation.

I had a miserable time getting the pump to work after I had carefully cleaned it, resealed it, and put it back together. I was convinced that I had put it back together properly and in the end that proved to be correct... although I took it on and off the car another FIVE times before I found out what was wrong.

I went through 5 litres of ATF getting it to work and all that was wrong was a tiny bit of grit on an internal shuttle valve...

...as it is often said here what a PITA!

I'll post some pictures of the offending part when I get them off of the camera.
