    The pump took an age to remove. I couldn't do it without removing the starter motor first. I have no idea how any could do the job with it still in place.
    I stripped all three pump covers, removing & replacing the seals, including the conical in its correct position. The screws were so tight I needed to use a sharpish-ended chisel to crack their tension before I could unscrew them.
    I have to add, that no-where did anyone state that the three pump covers were face-to-face, because they are not! There is a slight gap between the faces/surfaces. In point of fact, when the pump's three covers are removed (one at a time) there is a whole lot of crap to be cleaned away before any remedial work can be carried out.

    I was under the impression these were mating-surfaces, but they are deffinitely not. I cleaned them and refitted them, with light shown between the upper & lower surfaces after they were screwed together again.

    Jeez, I'm hoping all will be well tomorrow when after reconnecting everything the system is fuel-tight.

    I will add this, one of the best tools you can have in your kit is a piece of piping/steel-tubing. It makes an excellent extension to most tools and gives you an edge when it comes to tightening.

    Oh, the Torx screws are s**t (merde). They give no real amount of purchase and are easily rounded-off. Allen screws would be much, much better. So, if anyone knows the thread-size can they please pass it on. And if I learn what the size is I will have a dozen in stock (in my nuts & bolts box) just in case I need to do the whole thing again. Torx are really s**t. If you can, replace any you find as you go through a job. They are a pain.
    And... when I undid the pump, with all the correct extraction tools, etc, in place, the lower mounting nut, which you cannot see, fell into the void beneath.
    I searched for this nut and couldn't locate it, using an LED torch and bent piece of 3mm (1/8th) wire. By the way, the wire ended up going through my right-hand's little finger - passing close to the bone, I reckon. My fault. The blood flowed like there was no tomorrow and splashed everywhere (Aztecs sacrificed blood for better times, I've done it for no-leaks, lol).

    The good news is... after swelling, and being a bit stiff, my finger stopped leaking the red-stuff and the swelling quickly subsided. I'm left with no swelling or stiffness; only a slight oozing from both holes. The wire went through the muscle and has all but healed itself. I'll also say this, I have never taken any anti-biotics for over 17 years, so believe my immune system is up-to-scratch, no pun intended. My finger is working, bending as well as ever with no pain, numbness or stiffness at all. I just have this hole that passes through it.
    Anyway, the pump and the blind-nut beneath? To refit it, I used a different nut as I could not locate the original. I had to use a mirror & torch to see where the stud was in relation to fitting the replacement. That worked well, and my wife helped by supplying a small mirror for the purpose.

    All-in-all, this job is a real bugger. I hope I never need to do it ever again. I'm not religious, by any stretch of the imagination, but I'm praying the pump will not leak when pressure is applied.

    I am aware others have done this and they say it's kind of easy or straightforward. I, on the other hand, have found it to quite strenuous, not forgetting bloody!

    The drive belts too, are a pain in the proverbial. The smaller of the two was a trial, but turning the engine-over with a socket helped. If you can imaging fitting a tyre onto a bicycle rim the idea will give you an idea of how to do it.
    The larger belt has been left for tomorrow. As well as fitting everything else that needs to be.
    I have taken some photo's, but not as many as I meant to. These will be shown when all is finished.
    The seals, by the way. I bought them off Ebay.uk and the selling firm asked for the Pump Label numbers so they could send the correct kit. They did. I will also pass on their info too.
    As for now, I'm off to bed, to dream of a sealed pump and a fixed finger. o_O

    The pump heads look like this when removed. 20171029_103919.jpg
    There's a lovely gap for water to get in and cause corrosion.
    This makes sealing them up again very tricky. Mine is still leaking after I changed the seals. So when I do it again, I'm going to reface the heads and body.
    The body gets equally rusty too and the piston head suffers putting. 20171029_121910.jpg All these problems can cause leaking or creeping of diesel, like mine:mad:.
    Oh and yes, you do need to remove the starter.
    There's no need to touch the drive belts though. It's about an hour or so to get the pump off, once it's been done a couple of times.

    Hi Nodge, and thanks for the photo's. Great quality showing the mess thay can get into.
    I wrote a detailed account yesterday, but we had a power outage so lost everything written.
    My 2nd attempt...
    I agree with what you say, Nodge, about not needing to remove the belts for this task. However, I was replacing the belts for new. One was severely cracked while the other was very good. I'll carry them on-board as make-do spares.

    I was also going to replace the coolant-pump & thermostat, but with the belts off, the coolant-pump rotated smoothly and without any play. I left it in situ. I'll still replace the coolant though, maybe next week.

    The fuel pump... phew. I tried to do the job but the starter motor was in the way. It wasn't a big deal to remove it, but should I need to get access to the fuel-pump again I'll try what you say and leave it alone. If others can do the job with the starter still connected then I should be able to as well.

    Now, the results of my efforts and subsequent blood-loss. The sacrifice worked. The pump is as tight-as-a-drum, it appears. I've had it out for a test run twice. The 1st was yesterday after completeing the job in hand, plus this morning from a chilly start. So far so good. I'm toying with the idea of buying a used pump to recondition it myself, and will be a standby measure. I have an idea of a small modification too. But that's still to be worked out.

    By the way - and this might be of interest to some, after screwing on each of the 3 pump-covers, tightening the Torx screws as much as humanly possible, I used a G-clamp to press the covers down, trying my best to make the pump tight and sealed. The clamp made no difference as there was no more movement to be gained. And I really clamped it! I pinched each screw with a final chizel hit, just to make sure it was tight. The Torx heads would allow me to use my Torque wrench as my sockets & Allen-type keys just slipped out.
    I'm still hoping to find replacement screws, Allen-headed & stainless. I just need to know the screw thread, etc first. Help?

    I bought the Seal Kit from... interspares2000 (Ebay Handle) for £12.98
