FUEL PRESSURE ALARM

Who's the expert? Methinks alarm limits have been set to narrow . . . .

GRT Model 4000 Engine Information System. Fuel Pressure alarm periodically flashes when fuel pressure seems appropriate. Mattituck IO 360 MAX 45 PSI MIN 14 PSI. But where do I find these limits? I think I have determined they are an AUX input.

(I am not at the plane and it may become apparent when I am scrolling through the EIS screens)

Yes

AUX 1-6 are assigned. Go to set pages. . when set up your Aux ports, most name them left right ( fuel) , fuel pressure, Amps etc. so you know which aux has been setup for what. Me, #5 is fuel pressure.

See page 7 in EIS4000/6000 pdf.

I believe the limits your asking for are in the engine operating manual.
