    heat shrinkable nylon fuel pipe - where to buy?

    As per subject, looking for 6mm ID nylon fuel pipe, heat shrinkable. The injector nozzle connector is from a BMW 1200 and as received had a short length of this type of pipe attached. Space around the connector is limited and normal 12mm or thereabouts OD pipe with a clamp wont bend enough to fit the space. Prefer to purchase by the meter if possible. Alternatively a right angle injector connector would work, but havent been able to locate any
    it's not a bad thing till you throw a KLR into the mix.

    Did you have any luck with this ? The nylon tubing is a standard pressure line size, I'd have thought that a HD heat shrink over the top could have been the way to go.

    Hmmm
    Electrical heat shrink shrinks with heat but not really really tight. Then softens again if it warms up...

    Nothing so far. The original BMW pipe is really tough, electrical heat shrink doesn't come even close. This stuff is about 1.05mm wall thickness and 8mm OD. (shiny black if that counts for anything)

    I'll ask on the Speeduino (thats the Arduino based controller I am using) forums and report back if anything comes up.

    Maybe its something like this: https://www.jegs.com/i/JEGS/555/159226/10002/-1
    The way it had appeared to compress abound the barb may have fooled me into thinking its heat shrinkable, where really the pipe has just gone rigid with age and engine heat. This stuff certainly looks the part.

    Have you actually been and talked to an EFI specialist about it ? That would have been my first step.

    What pressure does it see anyway ?

    Pump is regulated to 3 bar / 45 psi - not a lot. Most automotive EFI is fed from a common rail which connected straight to the injectors so flexible pipe is not used. If I knew of any EFI specialists I'd contact them, which is why I asked here.

    It's most likely not heat shrinkable; usually it's just nylons that's been heated up to soften it, pushed on & re-hardens conforming to the shape it's pushed onto.
    You can get nylon at places like Dynaflow/ENZED in Lower Hutt, Hydralink might also do it? & Leda in Upper Hutt make the stuff (but don't know if they'll sell to public tho if they do you'll have to buy a 20m length)

    Yellow pages are your friend. Couple of automotive EFI specialists here in ChCh so there should be some near you.

    You might think so...but I know of a few automotive specialists with no on-line presence.
    But most are traditionalists and have a listed phone.

    I thought I had no on-line presence, nor did I advertise traditionally. But I still got a steady stream of new customers who had read glowing references (from real clients) on trade websites I had never heard of.
    Oh and the local Facelook community page...

    It's everywhere!
