Default Elevated Fuel Pressure...

I get alarms for elevated fuel pressure on my D180. Fuel pressure is always at the top of the green arc, and most often into the yellow, and sometimes into the red which causes the alarm. Engine TT is 60 hours. I don't believe I can change alarm set point in the D180, nor can I adjust fuel pressure at the pump. Any suggestions appreciated...

If you engine has the newest style fuel pump the pressures run higher than previously and require slightly higher pressure limits.

Make sure you have the latest lock file loaded (available from Van's website in the downloads section).
