PLATE INSTALLATION
To install the plates, remove the six 5/32 allen-head screws from the regulator. Carefully remove the top cover, and put the first plate
under the diaphragm, as indicated in Figure 3. Install the second plate on top of the diaphragm, as shown in Figure 4. A very small
amount of RTV silicon should be put around the top, outer edge of the top plate. Install the top cover, and tighten the six all-head
screws.
PRESSURE RELIEF PORT
On the topside of the SR is a port that can be used to lower the slope of the curve and dampen transitions. It comes with
a “jet” that has no opening. If desired, this jet can be drilled out to decrease the slope of the fuel pressure/boost curve.
