The Racetech In-line Fuel Pressure Gauge Isolator allows the interior mounting of pressure gauges without the danger of having high pressure fuel lines within the driving compartment. Fitting the isolator between the pressure source and the gauge, when pressurised, the fluid pushes against a diaphragm inside the isolator, which transmits the pressure along an oil line connecting the isolator to the gauge. The corresponding fluid pressure is then displayed on the gauge.
The isolator comes with two male 1/8 BSP threads with concave fitment.
Please note: Designed for fuel injection systems only, as the pressure of a carburettor system isn’t enough to operate the valve.
