The most basic function of an automotive vacuum gauge is showing the difference between atmospheric pressure and the amount of vacuum in your engine’s intake manifold. The amount of vacuum present in your engine depends on the efficiency of your ignition system, valve train and much more. With a vacuum gauge you have a quick and easy way to diagnose your engine for certain problems. However, these automobile gauges are equally as useful in demonstrating whether your engine is performing at its best. For example, keeping your intake manifold steady with balanced vacuum levels can maximize your fuel economy. So when you have either an analog vacuum gauge or digital vacuum gauge, you’ll have access to a valuable resource which will help maintain your engine’s health over the long term.
A vacuum pressure gauge is an easy and inexpensive way to check on the condition of your engine as well as its performance. If you take readings directly from a source location such as the intake manifold, vacuum levels will give you a solid assessment of whether your engine is running well or if it is underperforming. Monitor and troubleshoot for issues such as a restricted exhaust, damaged manifold, faulty carburetor and more. Some indicators of vacuum problems to look for include high oil and fuel consumption, exhaust smoke and a rough idle. GlowShift’s vacuum gauge displays readings from -30 - 0 inHG which can alert you to potentially larger issues in your engine.
What’s the difference between a mechanical vacuum gauge and an electronic vacuum gauge?
GlowShift electronic vacuum gauges include a vacuum line and T-fitting that runs to your vehicle’s intake manifold, with power wiring which connects to a 12 volt source. Our mechanical vacuum gauges require no hardware or wiring and include a 1/8-27 NPT male thread on the back for vacuum lines and fittings.
Can I customize the look of my automotive vacuum pressure gauge?
Definitely. Select a GlowShift Gauge Series that defines the look of your truck or car vacuum gauge. Choose an analog or digital display, clear or tinted lens, multiple LED color modes for readings, and other variable features.
What’s included with GlowShift truck and car Vacuum Gauges?
Each 2-1/16” (52mm) automotive vacuum pressure gauge comes with a 6’ PVC Vacuum Line that has a 1/8” Inner Diameter, a 1/8” T-Fitting, 2’ Power Harness, Mounting Bracket, Mounting Hardware and Gauge Visor that protects the display from sun glare while taking readings.
