Folks,

My Fuel Flow Transducer has about 150 hrs on it hooked up to GRT Efis/EIS 4000. Worked great then took turns reading either zero or correctly. The other day, bounced between zero and 30+GPH. Faulty transducer? EIS? Wiring? Whatcha think?

Yes, I will call GRT, but thought I'd get feedback here first...

Thanks all,

Jerry Cochran

Where is it mounted in the fuel system? What type of fuel system do you have?

There might be some turbulence in the fuel line that’s causing an inaccurate reading.
