Vacuum Gauge

Thought somebody might find this useful if you are having vacuum issues and want to learn a little more about your engine. You can make one of these with some fuel hose slipped onto an over the counter vacuum gauge, super cheap.

Vaacum guages are great tools, Mine however is somewhat exotic it initially saw service in the cockpit of a WW2 P400 Aircobra in the South Pacific brilliant bit of gear for diagnosis work though and even a cheapy is worth the effort they will save you countless hours when diagnosing problems.

I have mine permanently under the hood.  The needle is a little shakey when cold but when warmed up it sits solidly on 21" at idle.  I also love my Wideband O2 sensor.

 

Both these tools are excellent for tuning and diagnosis.post-24616-0-03647300-1408756619_thumb.jpgpost-24616-0-70370800-1408756632_thumb.jpgpost-24616-0-07808700-1408756644_thumb.jpg
