    You did it wrong then. All new seals kits should be Viton. The original seals fitted do not like the additives in modern diesel.

    Not surprised. I was playing with diesel at the weekend. The old stuff actually felt oily on your fingers. The modern stuff is more like petrol. I kept sniffing it to make sure I was dealing with the right stuff. very strange.

    There are Bosch pump seal kits on eBay for around £15-£20. That's where I got mine from anyway. Same pump on Rangie, Omega, BMW, some Volkswagens.

    I agree. Modern diesel with no sulphur and a lot of bio, is a very dry fuel, which doesn't lubricate pump internals like it used to.

    I always use a lubricity additive, like Eco Max, in older engines.

    That's a good tip. Can you feel the difference with your fingers? I don't think there's much lubrication in the diesel I put in: it was bog-standard ESSO stuff. i don't want another FIP failure.

    Eco max is incredibly slippery, and you can feel it between your fingers. I don't think that is recommended, though, it is probably pretty toxic.
    It also adds a few cetane numbers to the fuel, so you should get good MPG.
    And it isn't that expensive, due to the high dilution that is used.
    Some people mess around with 2 stroke oil, I have not seen good results from doing that, I have never seen how it would match up to a purpose designed product.

    Other excellent fuel additives are available.

    Could be wear on the shaft where the seal has been riding on it.

    There is no shaft to wear. It is the O'ring seal pressure head to pump body.

    Fair enough, hadn't been following it. I assumed it was round a rotating shaft.

    If it is well lubed up and carefully fitted it should be a simple task.

    Those pumps fight back. Getting it tightened up without movement is very hard, even when you've scored it on all sides.
