GlowShift Gauges Support

Yes! Most of our Fuel Pressure Gauges are compatible with returnless fuel systems, with the exception of the Tinted Series (GS-T11). The Tinted Series uses a diaphragm-style sensor that can experience excessive wear when used with a returnless fuel system, which may cause the sensor to fail prematurely.

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.
