Our industrial and marine gauges can help alert you to a variety of conditions, including measuring the hours of use for a particular engine, measuring the voltage and amps of the electrical supply, checking the fuel levels, relaying water levels and measuring engine speed. In addition, these gauges can help save time and effort later on, by quickly identifying where the engine might be having problems.

Our oil pressure, oil temperature and water temperature gauges are critical to identifying a malfunctioning pump, bad blower, engine leaks and much more. If you don’t have any on your engine or transmission yet, we highly recommend that you consider buying one of these units. Even if they do not remain attached to the engine, it is a good idea to have one nearby, to help with diagnostics. In fact, many mechanics keep one on hand as a useful way to quickly identify problems. 

We also include a useful graphic to help with the installation process. Whenever you find the one that you want, simply click on the '+ Pictures' button. This will provide you with more product details, as well as having a useful link that will have clear, easy to read diagrams outlining the proper connections, installation and precautions.
