    Hello,
    Are there any vacume lines that run to any part of the 4WD system on a 1985 K5 Blazer with a TH350, np208 and stock 3.73 gears?
    Thanks
    Adam

    No.

    TH350 uses a vacuum modulator, but that is not 4wd specific.

    Ditto. Just the vacuum line to the modulator from a manifold vacuum source.

    There are some small rubber hoses, but they are just vent tubes.
