Paging the fuel pump gurus

Discussion in 'UK Motorcycles' started by Paul Carmichael, Mar 22, 2010.

  1. Mate of mine has a yonks old Yamaha Genesis. The fuel pump stopped working
    and he assumed it had something to do with the relay.

    Yesterday I took the pump apart and the contacts were a bit shite, so I
    cleaned them up, adjusted the spring a bit, sprayed the whole lot with
    switch cleaner and tested it. The solenoid activates, pushing the contacts
    apart, but the solenoid stays activated. I can clearly see the gap between
    the contacts. I don't know how many bikes have this type of non-return pump,
    maybe someone here knows if there is a pump available these days to replace
    it? I'm assuming that either the insulation around the contacts is no longer
    insulating, or something is wrong inside the pump body, leaving the solenoid
    permanently connected.

    What say those that know?

  3. Thanks.

    Some cheeky folks about. Wants 40 quid second hand. I've emailed him about
    shipping to Spain.

  4. That was the whole point, hence:
    Yup, figured that.
    No, the solenoid is pushing hard.

    Yebbut that's only about three Euro at today's rate.

    Happy to forward it on if you want to get it sent to me.

  6. All my hoard is in pounds sterling. I'm a little unhappy.

    Guessing a bit here, but I've come across some electromagnetic brakes in my
    line of work that effectively have a bit of an over centre operation. Once
    operated they don't like to spring back. It may just be a case of fine
    tuning the spring slightly.


    Rusted and ropy.
    Dog-eared old copy.
    Vintage and classic,
    or just plain Jurassic:
    all words to describe me.

  8. Thanks. I bought it with GBP8 delivery to Spain. I think it was GBP5 to
    Blighty, so not too bad.

    I made an offer of GBP30, which was automatically rejected. So how does this
    offer thing work then, if offers are automatically rejected? If it had been
    for me, I might have made more of an effort to knock him down, but my mate
    just said to get him a pump.

    If there's a best offer, you know they'll take a lower price, so worth a
    try. If they have it set up automatically, you get three chances to
    guess what they've set the number at, after that you can't make any more
