Looks like my Power Steering pump is a bit different, so I'm still struggling with this - epecially the rear bracket that I cant even tell which way around it is meant to be. Seems quite a bit different to the other pics

What you have there is a 6B pump, like mine. I suppose it's quite possible you have a set of brackets made to attach to a Cologne engine. Are you sure the kit you have has been, at some time, mounted on your Essex engine? I will take some more pics of my set-up, trying to show more of the rear bracket which is a bit complicated because there should be a bracket fixed to the pump, which then attaches to another bracket fixed to the engine. There are two short bolts at the back, one of which acts as the pivot between the two brackets, and the other clamps into the curved slot. I found it was necesary to spot-weld the head of the head of this second bolt because once the whole lot is mounted on the engine, you can't get a spanner on it -but you can get a spanner on the nut which should be on the outside(facing backwards). Clear as mud? - more pictures when I can get to it. :D

It certainly seems to be the same shape pump as is shown for a 6B but I thought yours was an Essex?.
The pump has never been fitted to this engine as I bought it with a power rack and a few other bits as a job lot but I never even saw the car
The front bracket does seem to go onto the Essex timing cover nicely which suggests it is intended to go onto one though.

It's the rear bracket that is confusing me. I noticed that yours seems to have two bits of bracket on the rear, one of which is triangular-ish. I don't have anything like that but then again the bracket I do have is different to either of yours.
The pump does seem to be the same shape as yours but the pipe connections are a bit different (probably just a different year) which may explain why the bracketry is a bit different too.

The main thing I cant make out is how the belt tension is adjusted on the rear. Its also odd that my rear bracket seems to have two fixing holes when there is only one on the pump - suggesting that both holes are fixed to the engine (ie not how I've photographed it) but there doesn't seem to be anything to bolt a second one onto the block

Does that pump have one or two fixing points?
Does anyone have a pic of the rear of a round body SE6a PAS pump? Does that have two fixing holes?

Although my pump only has one, I suppose an the pipe plumbing connection point could be used

Yes, my car is a late 6A with an Essex engine, and the style of pump which was fitted to the 6B. It looks to me as though the front bracket you have fixed to the timing cover is not the correct one. Look at my picture here:
IMG_20181013_141428.jpg
IMG_20181013_141428.jpg (138.58 KiB) Viewed 418 times
You can see that this one stands higher than yours, ie: it is angled upwards.( I also think you will have to move the fuel pump.)
Now look at the back of my installation:

Here you can see that there is a bracket shaped like a sickle screwed to the cylinder-head( not the timing cover) with ONE bolt. Then it loops round the rigid pipe, and attaches to a second ,smaller bracket which is fixed to the pump with ONE STUD. Then connecting the two brackets are TWO short bolts, the nearest one being the pivot. You can just see that the furthest(lower) bolt slides in the curved slot to allow tensioning of the belt. So there are TWO clamp-bolts for tensioning, one you can see here and one at the front of the engine. This rear one has the nut completely hidden (you are looking at the head,partly hidden behind the plastic sleeve) so while I had the bracket off the engine, I tack-welded the nut in place. For adjustment, I slacken the Front slider, the Front pivot, the Rear pivot, and the Rear slider - but NOT the fixed studs.
This last picture is looking donwards at the front of the pump, between the body and the pulley. On the right of the picture(left of car) is the Front pivot; and on the left of the picture is the Front slider:

Thanks for those pics Oldconn. Yours is def different to mine. Actually if you look at the diagram Scimjim put up on the previous page, the upper diagram looks just like mine except that the pump has a round body. so Now I wonder if I have some kind of hybrid round pump/ rhomboid pump setup. The answer will come if someone can tell me if the round pump has 1 or two mountings on the back.
Meanwhile I am searching high and low for the rubber hydraulic pipes in case there is something attached to them - I know I've got them somewhere.....

I don't think you have a hybrid pump, I think there were only ever two types( as far as I know, could be wrong) and yours is the same as mine. About the time of the changeover 6A/6B a few bits were common to both , the only modifications made were to acommodate the Cologne engine.

Actually, there may be three types, because the early round type (in the first diagram on the previous page) and the later round type (in the second diagram in the previous page) have different part numbers (perhaps the reason for the change of brackets?).
My late '78 and early '79 Se6as both have the round type and the brackets as per the second diagram (as you'd expect), the brackets look the same as oldconn's which tends to suggest that the later pumps may interchange (provided you have the later brackets). However, comparing with the diagram, it looks suspiciously as if you may have the earlier brackets? Is yours an early car (or perhaps an early engine? And, Ian, do you know if your pump is original?

maybe even four types? My square/rhomboid one has different pipe connections to OldConn's

I don't know if my car left the factory with this pump on it, but I have never changed it. Could have been changed by a PO, I suppose, but the brackets are definitely factory items, no way they were cobbled up by a home-mechanic!

Here are today's pics which clearly show how the bracket & the pump all fit together.

A spacer is required for the top mount to fit, about 3/8" would do.

I havnt been here for a few days.

Oldconn - wow I hope you did not dismantle the car just to get photos!
There is no doubt that you bracket is different to mine though - min looks like the one in the parts book but your's doesn't - probably a different year. I also noticed your comment about moving the fuel pump which I see is blanked off. Doesn't look necessary so far on mine ..

Does any one else have pictures using the bracket shown in the parts book?

I seem to have lost one of the hydraulic pipes - the low pressure one I think as the one I have has crimped hydraulic fittings at both ends whereas it looks like the other on is just a push on at the pump end. I suppose this could have been ordinary rubber pipe most of the way but presumably it at least had a metal fitting at the rack end.
Any advice on getting a replacement?

Oldconn's bracket looks the same as mine (ie the later Se6a bracket as in the second pic in Jim's note on the last page). Your bracket as far as I can see looks like the older bracket (as in the first pic). Is your engine original to the car? (and what age is the car?).

The low pressure pipe has a rubber section about the same length as the high pressure one, but only an ordinary fitting onto the stub pipe on the pump and the metal pipe, which then goes all the rest of the way down to the rack
