Ip leak From here, any ideas ?

There's a large O ring under the pumps distributer head.
On the join about an inch to the right of the bolt you have circled.
I believe it's possible to do in situ if you are careful and do not remove all the bolts at the same time that hold the distributer head on.
I would clean it up spotless first though just incase it's leaking somewhere else and just ending up where you're circled.

Thanks that would seem to be it.

Think I have also seen a youtube video for the same job.

I think I will change the pump as I have a spare, only problem is I don’t have the pump locking tool but have made this ,any constructive criticism why it will or won’t work?

Made what?
