I have a returnless fuel system, can I install a fuel pressure gauge?

Yes, all of our Fuel Pressure Gauges with the exception of the Tinted Series (GS-T11, GS-T11_30) can be used with a returnless fuel system. Unfortunately, due to the diaphragm style sensor used with the Tinted Series Gauges, a returnless fuel system can put excessive wear on the sensor causing them to fail prematurely.
