Update on the failure
To update everyone. I posted originally that the fuel flow sensor quit (at 20 hrs). Next, I flowed a lot of fuel thru it into a gas can. Must have unstuck the rotor inside because it started working again. After about 1/2 hour of flight time, it quit again.
Current situation.. troubleshooting determined the problem was the red cube, not the wiring. After getting another red cube.. standing on my head for hours, the red cube was replaced and now works again.
FYI. The cube is mounted in the tunnel after the booster pump and filter just as Van's directed me to do. The tunnel is vented and does't get over 150 degrees. Don't know why these fail... heat, vibration, etc...
