    Vacuum hoses

    While Iím waiting for the TPS to arrive from Italy, Iím going to change out all the vacuum lines.
    My question is what sizes and length do I need? Also, should I change the fittings?

    I can't imagine that anyone is going to give you a detailed answer to those questions, so short of ordering everything from AF1, if even possible, just take copious photographs of existing line routing/installation and even tag the lines with ID info, then pull them and take all the pieces to a GOOD auto parts store for duplication. Then pay LOTS of attention when installing the new goodies.

    On second thought, there's only a couple sizes of the tubing used, so just go buy a couple feet of each and cut/replace sequentially in lieu of yanking everything off.

    Yes, get the unions/connectors, too.

    I replaced all of my OEM vacuum tubing with platinum cured silicone tubing (stays shiny even when old) off of Amazon:

    I just replaced each piece by pulling a single one off individually, cutting the proper length, and replacing it, with new connectors as I went.

    I also replaced all of the oil lines and IAC lines with 9.5mm and 13mm Flourosilicone hoses from AutoSiliconeHoses (ASH):

    Did you order the fluorosilicone lines from the UK? Or were you able to find a US distributor?

    Would you be willing to sell your leftover tubing, or is there not enough to do a second bike?

    This is the sort of project I like to take care of when I have things apart anyway, but it's like picking a thread on a sweater...once you start, you notice those rusty bolts over there that you could replace with stainless, and before you know it, you have a jigsaw puzzle on your garage floor!

    I did order them from the UK. I can look if I have enough for a second bike.

    spacewrench,

    I'll likely do mine this winter, and am pretty close to you. We could split resources if infrasoundxp doesn't have enough.

    I have enough 11mm left (used for large oil line) for another 2 bikes probably, but not enough 9.5mm. Only have enough 9.5mm for one of the oil lines on the bottom of one bike and not for the IAC lines.
