If extremely fine pressure regulation is desired, two regulators can be installed in parallel, see table at right. Connect the two inlets together and connect the two outlets together. This should not be needed except on larger gasoline big block engines, or engines that run methanol. There are many regulators; call us; we will recommend the best setup for you.

The primary pressure relief valve does this, and also regulates the pressure at about 15 PSI* to the inlet of the regulator valve. It is necessary to keep the inlet supply pressure to the carburetor regulator valve at least 1 PSI above the maximum desired regulated pressure, but not more than 20 PSI total to prevent damage to the regulator. NOTE : the fuel filter is placed before the valves so that it will protect both the relief and regulator valves.
