    Dear All
    Our Kigass until recently has not been working but I have received very good advice from several members and following stripping down it now works! However..upon stripping down we notice that the smaller diam copper pipe (kigass to carb) in one place has been badly squashed, can anyone point us in the direction of a suitable supplier of such pipe? Its seems prudent to replace even though it now works, as the supply may be impaired in the future. thank you in advance of your help.
    Kind regards

    Dear Richard,
    I had to replace the copper pipe Ki-Gas to Carb on my 16/80.
    The Complete Automobilist (aka Vintage Supplies) stock most pipe sizes.
    01692 406510 or have a look on their website http://www.completeautomobilist.com

    Incidentaly whilst visiting France earlier this year I saw the remains of a MK1b Spitfire in a museum. Amoungst the remains was a Ki-Gas unit identicle to the one in my car.
    I guess that even the carbs on a spitfire had to be primed.

    Best Regards

    Hi Richard,

    Squashed Ki-Gas pipe is a common complaint which, as Chris mentioned, can be remedied with new pipe. It should be silver soldered but do not use too much heat as the brass fittings can be easily melted.There are different grades (and meting points) of silver solder. If you do not feel confident to do this yourself, go and see someone who makes jewellery.

    The Ki-Gas was also fitted to the Churchill tank but the pump is quite a chunky affair with a “T” shaped handle as opposed to the dainty circular top of ones on a Lagonda.

    hi sorry to post something that isnt relevant but was wondering how to get the information on stripping down and modifing the ki-gas pump to put the new seals in it as mines is letting the fluid flow out of the pump handle lol. as for your problem with the pipe it depends on the fitments on either end of the pipe as for mine i made one out of copper brake line with the aid of a brake pipe flaring tool

    any help would be greatly appreciated

    Hi all,
    We have been away on a Lagonda holiday for the last 2 weeks so have not sent any e-mail responses as the documents are on my PC at home.
    Will forward them when I get back later this week

    Can I revive this thread from 2011 and ask if anyone can point me to instructions on how to rebuild my Ki-Gass pump? My 16/80 starts very easily without priming but as the pump is there I would like it to work even if it seems I don’t need it! Thanks Rich…

    There is zero resistance in the pumping action so there is almost certainly no petrol being pumped. When I first got the car 3 years ago you could feel the fuel being pumped after a few pumps but now it just feels empty. I haven’t worried too much because the car starts ok.

    It’s not a complicated thing Richard, but it is a bit fiddly. A few ball bearings, springs, a diaphragm and graphite cord top seal the shaft. I think the piston has a square section o-ring that could need replacing. Once you start stripping it you’ll need to perservere though. I have some graphite cord left over from when I did the one on my Aston. You’re welcome to it.

    I’m by no means an expert but if there’f no resistance my guess is that the spring/ball is gummed up and will just need cleaning. I am pretty sure that some vintage tractors used these as well and that you can by a service kit. aerovintagespares.com used to sell replacements once but I’ve no idea if they still do.

    Good luck,

    Hi Richard,
    Check in the clubs old technical bulletins.
    There is somewhere a how to rebuild of the kigass pump (they fitted these pumps to the Spitfire and Hurricane by the way).
    The club spares also stock the ball bearings.
    Best Regards
