    November last year I bought a Sigg Firejet for cheap, because it was listed as 'needs work'

    And since I'm not one to pass up a great deal, I decided to snatch it.
    It came in it's original pouch, pump and it's original pricker.
    And I finally got around to get a maintenance kit from Basecamp, as they are, as far as I can see, the only ones in the world who still sells those.

    A fun fact about these stoves is that you can switch between white gas/Coleman fuel and kerosene almost on the fly(if you switch bottles fast enough). There is a lever on the burner which you have to set on 'A' to burn white gas and on 'B' to burn kero. No fiddling with nipples or anything, just flip a switch!

    All it needed was a new washer in a bolt underneath the burner.

    This is where you prick the yet if it's clogged, a rather odd place if you ask me. But there is a nylon washer here that leaked.
    After replacing that, it was time to use it:

    It is a very capable burner, but it doesn't simmer that well. The burner itself seems capable enough, but the regulator on the pump is more of an one-off type and doesn't really regulate.
    So brewing a cup of coffee on this is not really recommended, I'm afraid... Don't ask me how I know 8]

    I have one with a bad hose that I am going to work on someday. That seems to be a weakness.

    Did the kit come with the heat-resistant seal for the bottom? If so, I'll need to order a few kits.

    Yes, it does. I also mention this in my original post. You can however also order them separately if you need only the nylon washers from here

    I have to admit that this stove, made in my city (Geneva) by a friend for sigg, suffer from a lot of design flaws, its a pity that sigg never realy tried to make it better, the production was cancelled short after the first batch.

    There were a lot of other stoves on the market at the time, so the market share of any one model would likely be small. Still, I thought it was an interesting design and am sorry that Sigg didn't continue to refine it.

    These stoves actually runs great on a butane Canister with its standard jet, if you can add an adapter like this in-sted of the pump-adapter on its fuel line, as the plastic pump with its thin housing is a weak construction IMG_4682.jpeg

    Much easier to light and can even simmer a bit easier on the butane Canister.

    I have the chance to buy a firejet without a fuel line or pump. Can someone advise the best pump and fuel line replacement? I emailed bearniedawg for thread/fuel line adapter..

    any advice will help

    As long as you can have someone to make at least a fuel line fitting the thread at the stove end and then a thread known to fit for example Primus pumps and the propane/butane gas canisters at the other you should be OK. The original pump has always been the weak part of this Stove. (This might cost you the same as a complete stove in the end)
    (The Sigg Firejet runs great on regular cheap camping Propane/Butane canisters without changing jet).

    If I'd make/get a butane/propane conversion I would seriously pressure test the adaptor and line setup. That's why I like liquid stoves. If it leaks, you can where it leaks, with gas, that is harder to spot.
