    Where to tap boost line

    Hey guys. I'm looking to run a boost Gauge on my ski.

    There are 3 nipples coming off the manifold, but they are being used by my fogging kit.

    Are there any other nipples that I can tap into?

    Would I be able to remove a fogging line from the middle manifold nipple and run the boost line to that?

    Also
    When I attach the oil bottle to the fogging line there is always vacuum. Even when I give it a few blips of the throttle it is always sucking air into the manifold. How would it give me a boost reading?
    Has confused me. .

    You won't see Boost in your Manifold until at least 5-6k or more.

    You could always tap a 1/8th fitting into one of the runners. I went in just above the MAP sensor. The plastic is thick enough.

    the SC does not make any boost until about 6000rpm
    so vacuum is normal

    What would I use to tap into the manifold?

    I have seen people tap into the throttle body.

    Just up from the Map sensor is where LesCooke recommended tapping in for a reference line for Boost. I used a Brass 1/8th NPT Air fitting and sealed it with thread locker when srewing in. Worked mint.

    Did you just drill into it with a drill bit, then screw the air fitting in?

    No, no. Drilled the appropiate size hole and tapped threads into. The plastic is a fibre reinforced and taps pretty well.
