I have a JPI EDM-700 with fuel flow and it seems like every few months when I check the calibration, I have to adjust the K-factor. The adjustments are all in the same direction - I'm using more than the JPI indicates. This last time, after a 43 gallon fill up, I'm down to 14 gallons actual and my JPI says I should have 19 remaining. Is it normal for fuel flow sensors to creep like this? I haven't been using the boost pump which I know will effect the readings. I'm pretty sure my sensor is a FloScan rather than the "Red Cube". Carbureted engine.
