Well after a day and a half I've given up on this little bugger.
Will not budge and I fear that any further attempts will damage something.
This is what I was dealing with, down in a recess with just 2 small flats to grip and it is supposed to unscrew. Can't get anything substantial down there, it just laughed at needle nosed pliers:
It measured 7/16" across the flats so I sacrificed an 11mm socket and made this:
Alas, It simply screwed itself off and after several tries with a little refining inbetween I gave up on that and asked for help from the forum.

The discussion is still going but I didn't get much joy there. Suppose that not too many had dissembled an early OD. I did get a suggestion which I had thought of and that was to press a piece of tube over the socket to give it more support.
Today I did that and here's a picture of the reinforced socket in the hole ready to try.
But a similar result and the socket simply screwed itself out again.
It just doesn't want to unscrew. I toyed with the idea of having one more go machining a much more closely fitting tool all around the part and here is the start of that.
But to be honest I've simply lost motivation with that and have finally decided to 'let sleeping dogs lie'
The pump can remain in there as it is and I will simply flush it out as much as possible. I don't want to run the risk of damaging it. I did get the whole thing to move slightly but that was with more force than I felt comfortable putting on the part.
So we move on!
