Fuel System Vacuum Gauge

This gauge is designed to measure the vacuum on the suction side of the pump after a pre-pump filter. This tells you the condition of your filter element. As the element gets closer to it's used capacity, the vacuum will increase on the gauge telling you it's time to change the filter. Has standard 1/8" NPT male connection. You may need to install a threaded tee in the line to install the gauge.

Note: These are not intended for use with standard pillar syle gauge pods. They are approximately 1.5" in diameter.
