intermittent fuel level indication
I had the right tank float (standard Van's) level indicator fail at the worst possible time: during a 2.5 hour IFR proficiency flight. The indicator on the AFS 5500 was stuck at 15+ gallons and I was so preoccupied that it never occurred to me to question the reading and I almost ran the tank dry...scary.
The failure is intermittent, it jumps back and forth randomly between the accurate reading and showing full. I checked the ground and added an extra star washer on the mounting bolts. No luck. Seems that if the float was sticking at the top it wouldn't go back to a 'full' reading after showing say, 6 gallons.
Wondering what to check next and whether anyone has seen the same thing on Van's float indicators
