    What pieces do you need?

    That cap I measured is from a weak fuel pump. I still have some of the bits from it laying around. Was planning to garbify the whole thing this week or next.

    I can mail you some pieces, if it would help.

    well this could be of great help.

    what i was trying to-do was try and keep the fuel pump as "seadoo" as possible for ease of replaceing in the future.

    i simply extended the length of the seadoo unit. but by doing just that with the msx gasket and screw on cap its just not good enough. so i either need to swap the guts into a msx unit. or try and make the cap (bit you measured) fit my current set up.

    idealy i would like a complete unit, minus all the pump and electrics. what do you have?
    how much would you want?


    thank you for being so helpfull.

    The rubber gasket is just visible in the first photo

    Basically postage costs is all I would ask.

    That cap has two unfilled openings with just the rubber seals present. One had the electrical connector which I have used elsewhere, the other had the fuel hose connections. Can you use the cap as it is in the photos?

    Do you need any of the other parts of the fuel pump 'body'?

    Let me go see what pieces I can reassemble from that pump and post a photo tomorrow.

    the empty cap is fine. and with the large rubber gasket would be great. i would also like the spiral spring. and the "open" metal cage the spiral spring goes around. and the plastic lower half with the gause fuel filter. (i dont need any wireing or sender parts) just the complete body would really help. this way i can copy beerdart and koshs set up.

    if you could see what bits you can spare/part with that i need and a photo of what you have will help heaps.

    ill be more than happy to pay shipping plus

    the fuel pump was the one thing i couldnt get with my msx 110 hull when i stripped the ski as that was the one thing the owner wanted.

    thanks

    One way valve (the little red rubber piece) retains the 'returned' fuel within pump body to maintain supply to fuel pump when main tank is sloshing near empty.

    I am guessing that the satchel contains a water absorbent compound.
