are converting from a GRT EIS system, you must disconnect the external resistor pull-up from 
the fuel pressure output. This will make the sensor output equivalent to the sensor supplied by 
Dynon Avionics. 
Injected engines: Use the 0-80 PSI sensor (Dynon P/N 100411-001). Crimp a standard #8 ring 
terminal onto the brown wire from pin 8. Unscrew the stud cap from the threaded stud. Place the 
ring terminal on the stud and secure the cap down sandwiching the ring terminal. If the 
connection between the sensor and your engine is non-metallic, you must connect the sensor case 
to ground through other means. The best way to accomplish this is by sandwiching a ground-
connected ring terminal between the sensor and the mating fitting. 
  Due to vibration issues, never connect the sensor directly to engine. 
  If you use Teflon tape or other seal, ensure the sensor casing still maintains a good 
connection to ground.
