Hi Gary,
 
I'm testing my PPA fuel = transfer=20 setup, and having a problem with the sensors -- they do not shut off the = Facets=20 when the header fuel level covers the high sensor.
My sensors are mounted = inside an=20 access plate tube that extends up from the bottom of the header tank, so = they  point upward, and the high sensor is about 3/4" from the top = of the=20 tank. 
Is that enough fuel coverage = of the=20 sensor point?  Dennis tested the sensors themslelves and said = they=20 were ok. PPA can't test the K-controllers any more ....
Also, the controller does = shut off the=20 Facets as they run a wing tank dry.
Any comments on the optical=20 sensors?
 
Thanks,
