Fuel pressure is dialed in using the preloaded set screw on top of the regulator.
Two interchangeable orifices are included with calculated flow diameters to match the fuel pump flow to the regulator. This permits the DMR to be used with practically any horsepower engine. Furthermore, this added precision will resist diaphragm flutter and optimize pressure stability. See the installation instructions for more details.This design has been tested to regulate over 1,200 liters per hour (see MORE DETAILS tab).NOTES:1. Compatible with all gasoline and ethanol blends of fuel. 2. For a 3AN vacuum signal adapter fitting, CLICK HERE. 3. It is not uncommon for pressure to bleed down when the fuel pump is turned off. This is not a sign of a malfunctioning regulator.
