++Sorry this is a little long++
I was doing about 70 mph and coming down a hill when I had to let off the loud pedal suddenly. My pressure monitor alarm sounded and I noted a large negative reading (digital display) while it was in the idle mode. When I was able to step on the pedal again, it went away. Then later while traveling a constant 40-45 I got a couple of intermitant alarms and again noted negative readings.
Pressure reading at idle is 10. 2 and WOT is about 3. 5 (post filter at the filter) for a brief moment then up to about 4. 0 for the rest of the time.
The pressure sensor has a wired ground line, so I know the alarm isn't because I lost the ground.
Fuel pressure guage... don't leave home with out it!!
