Terrance, and others,

 

I have the ppavionics fuel controller.  It works fine.  It is the simplest system to use.  Turn it on, it turns itself off or you can manually turn it off.  There is no complicated extra wiring, switches, lights, fuels hoses, check valves, floats, fuel valves, etc. associated with one-off designs.  It does sense when the wing tanks are dry and shut off and shows a blinking yellow light.  Green lights are lit when the pumps are running.

 

A word of caution.  The wing tank Facet pumps need to be in good condition for the controller to sense the freq. change.  I had old pumps and the controller would not turn off at dry tanks.  I replaced the 2 pumps with new ones and the controller worked fine.  Ppavionics wanted my old pumps to dissect them to determine the exact reason for their failure to work in conjunction with the controller.  So, I sent them to them.  Never heard a word back about it, even after a subsequent e-mail and phone call.

 

Also the LED indicator lights are difficult to see in direct sunlight.  I removed the diffusers behind the lighted buttons and that made it better.  But don't lose the "L" or the "R" behind the lighted buttons when you put it back together like I did (lost the "R").  I asked them for another.  Never got one.  Now I am flying around with no "R".  But that is better than flying around with no "L"...or whatever her name is.

 

Also, as Bob mentioned, there are differences between the Facet pumps, so make sure you get the correct one.  Look at the numbers on your existing pumps.  One of the Facet pumps is special use and has check valves in it for use in wing tip or auxiliary tanks.
