PeytonM Posted June 18, 2019 Report Share Posted June 18, 2019 I’ve had the above device installed as a standalone fuel flow system in my 201 for over 20 years and it’s performed flawlessly. Over the past month/ half dozen flights the flow readout has fluctuated wildly, from 2 to 100+ GPH! However, half the time it works fine, even during the same flight! Seems to always work during taxi. What’s your best guess: transducer going bad ($300+), bad connection? Someone suggest air leaks! No evidence of fuel leak. Why would it work one day and not the next? Quote Link to comment Share on other sites More sharing options...
N201MKTurbo Posted June 18, 2019 Report Share Posted June 18, 2019 It is dirty and full of fuel varnish. Take it off and fill it with Hopps #9 and let it sit over night. Hook up the input side, turn on the fuel pump and flush it out, then give it a try. If this works, great. if it doesn't, it didn't cost much... 1 Quote Link to comment Share on other sites More sharing options...
