Wait wait wait,  model airplane tubing is fine.  just
make sure you get

the kind that is for 'smoke oil' or diesel model engines' it is
called

tygon, typically comes in yellow see thru, and is cheap.  like 1
dollar

per foot.  Tygon is the brand name most model stores
carry.  HTH

  Gotta watch that Adrian.  Some model aircraft tubing is

  tubing meant

  for alcohol- nitromethane not diesel.  Diesek will eat it up

  think, maybe try a bit first, or if you don't have any, lemme know,

it isn't

  recommended

  for diesel model A/C engines, you are supposed to use neoprene.

    Scott, et al,,   This I must share. At my local
friendly hardware

    store I discovered they have bulk flex tubing(hose) meant for toy


  fuel

    powered

    aircraft. The sizes seem to be at least close to what our Diesel


  caddies use(

    3

    mm for fuel return from each injector) but I do not know the
other

  sizes(

    they

    can be measured using a drill bit and some math,, 1 mm = .0396 (


  from memory)

    )..I would not enjoy replacing the entire line, would rather


  splice in some

    copper which can easily be swedged one size larger.. Adrian the

         While I was changing injectors
and their return

    lines, I noticed



    dampness around the return hose that goes from a barbed
connection

  at

    the



    pump back towards the tank.  It seems to be of a
slightly larger

    diameter



    than the short return hoses that run from injector to injector
and

  back

    to



    the pump.



        I snipped a bit of the apparently larger
hose and

    plugged it back in,



    but noticed that the cloth covering was a bit

    brittle.  Apparently this



    isn't the first snip job; rather than making a gentle bend from


  the

    timing



    belt cover to the fitting on the pump, the shortened hose must


  make a

    rather



    severe bend.  I suspect that it won't be long until the
barb

    wears through



    and I have another leak.



        Does anyone know what size this hose is,
how long

    it is, and where I



    might find a suitable replacement?



        TIA,



        Scott Kair
