Army Jill pauses by the 42 Ford GPW

You know that sometimes people say life sucks.  However, a little vacuum in your life can help your diagnose what ails your jeep or provide confirmation that all is well.

The vacuum gauge can tell you much more then a simple compression check.

You may not have a port on an early manifold. Army Motors told the troops to drill a hole for the vacuum port. And I reckon to tap it for a plug as well. As an alternative you could fashion a spacer with a vacuum port for those jeeps that don’t have a port…and when you don’t want to drill a port.

If you would like to find out more about the WW2 jeep, especially the early history then check out, Jeep – Its development and procurement under the Quartermaster Corps, 1940-1942, for more information.  It was written in 1943 when the information was hot off the press.  It isn’t a perfect history.  Is history on a given subject every perfect?  Lots of footnotes to have you dig further, should you want too!
