Ah, I did wonder if you might have a spare or two.
I've actually sourced a couple and am waiting for them to arrive. I did get one but my mate who fettles the car told me it wouldn't fit.
Mine is leaking slightly and also has an issue with the join between the ally casting and the metal parts which isn't a surprise really. I'm at his mercy with stuff like this, hence the search for another pump.
I've been following your fun and games with the PAS on your V6 and was very pleased you got it sorted.
Why did you buy it? I'll tell you why I got mine, it was just for the noise it makes when you 'wring it's neck'.
It has only let me down twice, once the radiator went on the A1 at midnight, and the other was one of the head gaskets failed. It has had a 'little' bit of bodywork done, costing a few quid

Oh, and the rear suspension mounts failed, well, one totally, plus a couple of wings, and a door skin, but apart from that, it's been a great car. It doesn't do many miles due to fuel costs but hey ho, and I really enjoy driving it.
I will post some photos of it, one day.
On the pumps, I'll bear you in mind and see what I get through the post later this month.
Did you see my quest for trailing arms? We fitted straight ones from the four pot models. I've not pushed it much so hope all is ok, and they don't rub on the tyres.
Cheers.
