GlowShift Gauges Support

<p><span style="font-weight: 400;">After doing research and testing right here at Glowshift, we have found that a Vacuum gauge will not read when installing to a Diesel Engine application. The reason it will not read vacuum is that a diesel engine does not generate vacuum, unlike a gasoline engine which operates off vacuum.</span></p>

Will a Vacuum gauge work on a 1995-1998 6.5L Diesel?
