Hey Frank: I understand your mechanics dilema. He/she wants to make sure it
is correct, and probably has never worked on a vacuum system driven by a
venturi.
First of all, DO NOT use common AN fittings when installing the
components. Vacuum fittings are made which have a gradual sweep instead of a
sharp
bend and do not reduce the amount of air (RAPCO) is one kind. They cost about
two or three times the AN fittings but believe me it will really make a
difference.
Second, use a quality hose to move the air. The less expensive tubing
from Home Depot or Lowes will not maintain its shape and will cause a loss of
air flow.
Third, install the fittings with teflon tape (carefully so as not to get
any particles in the gyros) or some other form of sealant that will allow
the fitting to be positioned in a manner that provides the greatest air flow
i.e. the least change in direction of the flow the better.
Lastly, if your regulator is not marked, the largest opening goes to the
venturi and the smallest goes to the gauge. The other two go to the
individual instruments. Normally the are marked P, T, H and G in the order
described
above.
Questions? (I know nothing!)
