Terrence,
 
My PPA setup does not include the high/low header tank warning = system, as I=20 already have a triple redundancy header tank high/low warning=20 fuel system when I built the plane.  So I cannot help you on = that=20 aspect of your installation.  It is good that the controller is = working ok=20 with the wing tank pumps.  The following is a little history with = the=20 issues I had with the original PPA fuel controller = installation. 
 
As noted in my original post (partially listed below)  I had = to=20 replace the original Facet wing tank pumps (1987) that came with the = kit, as the=20 PPA fuel controller would not sense the change in the pumps when the = tanks were=20 dry and shut off the pumps.  With the new pumps (installed = about year=20 2001) the PPA controller system works fine.  At the time of the = pump issue,=20 Dennis at PPA requested my old original pumps, as they wanted = to dissect=20 them to determine what the issue was with them.  I gladly sent the = pumps to=20 them.  They never responded to my subsequent calls and e-mails = asking about=20 the outcome of the pump investigation.

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