    Halfrauds sell P9 (or is it R9) rated fuel hose with clips for about £5 - from memory 1 meter is enough from tank to carb.

    Not sure best place to get fuel filler hoses from.

  3. Assuming what you have fits right measure that and replace like for like. If your bus pipe has been modified in any way (likely) then asking anyone to advise you of standard size is like asking how long is a piece of string.

    The bundle kit from Machine 7 is as good as any but if you are still not sure, this might help: http://www.volksbolts.com/faq/fuelhose.htm

    Use SAE J30 R9 grade hose, there are better grades available (Gates Barricade for instance) but SAE J30 R9 is adequate for E10 fuel. And don’t buy hose from anywhere that doesn’t know what grade they sell but just say it’s suitable for all fuels.

    And don't use anything that's over-braided.

  7. yes as above like Joker says depending if it's been tinkered with. I changed the carbs from twin solex to single Weber and the inlet is a bigger diameter on the weber to my electric fuel pump than the fuel pump to tank outlet.
     
  8. Thanks all , I used the kit from machine 7 , as suggested by volkswombat and 77 westy , seems to do the trick thanks again Paul
     
  9. what's wrong with overbraided? (just out of interest...aside from the fact that it's not necessary unless you imagine the lines will be chaffing or close to exhaust headers, turbo pipes etc.)
     
  10. They rot faster than a whores gusset
    :)
     
  11. think that's more to do with the quality of the hose rather than any outer braiding, tbh, but I could be wrong....


    They rot faster than a whores gusset....nice analogy btw:D

    Think with the overbraided stuff it's also not as easy to see if the rubber has perished when it needs replacing (not that you should ever get to that stage!).
     
  13. Hi , I changed the braided hoses on mine because they were damp with fuel , the rubber must have perished over the years think they were original ones ,i didnt want to take any chances with them for the sake of £25 and about an hour of crawling underneath it freezing lol

    Yep. The overbraiding hides the fact the the rubber has split / perished until it gets so saturated it starts dripping.
    Not good stuff.
     
  15. Ahh! I see....so what you're saying is, it highlight's the fact that some of us are too lazy to check them on a regular basis;).....Sounds about right:D
    Some of the ebay stuff is pure tat...for that 'racer look':cool:

    Guess if you're running SC and FI and all the acronyms, you'd want a nice tidy install....some of the thin wall braided stuff is pretty standard on 'posh' motors....but then again, the folk who build these aren't the type to skimp on fuel line
