Vacuum Adjustable TBI Fuel Pressure Regulator

[dave w]

I've finished the CAD for a Vacuum Adjustable TBI Fuel Pressure Regulator. The simple design is low cost to CNC Machine. The downside to this design is having to use spacer washers to adjust the maximum fuel pressure. At low KPA's the fuel pressure is reduced to allow for better idle and reduced emissions. At high KPA's the fuel pressure is at maximum pressure to provide optimum performance.
