I'm assuming you're running rubber hose directly from the manifold to the gauge.
Make sure you are using vacuum hose. It has a heavier "wall" than rubber tubing, so it won't collapse.
Be sure you have the right sized vacuum hose with a good snug fit over the hose barbs.
Don't laugh: If you don't have some kind of a vacuum pump;get a piece of vacuum hose and run it from the gauge to the driver's seat and suck real hard, just to see if you get any kind of needle deflection. If you do have a pump, sit in the driver's seat and try it

Hope that helps a bit.
