REFLECTOR: Odd fuel pressure Problem

I don't either....

Not quite normal pressures though, about 8 psi low...  Also I'm not 
convinced that the sensor is linear, meaning it could have an erronious low 
pressure but near normal high pressure, Does that make sense.

hahahahahah :-)  Ah, that definitely makes me feel better!!  I'm smiling again!

If it had been just me, I might have continued on. Might...  But with a 
non-pilot passenger , who is also my wife, I am more than conservative in 
my flight decisions.
