Aeroflow Gel Filled Fuel Pressure Regulator (FPR) Gauge, 1/8NPT, 0-100PSi

This is a gel filled fuel pressure gauge which reads from 0 to 100 PSi.

The gel in the gauge stops the needle from vibrating making for a more accurate reading.

FPR gauges should only be used for setting the fuel pressure, once set the gauge should be removed and the port blanked.
