My plane has flown great the past year and I am starting my 1st condition inspection. One of the few squawks I've had is my fuel flow has been fluctuating the last couple of months. One minute it is reading 8.2 gph and the next minute it will go to 9-10 gph. I recently completed a trip where the fuel flow was reading like this sometimes as high as 10 gph for a 3.5 hr stretch in LOP cruise and then go back down to 8.2gph without changing any cruise settings. I stopped to fill up and my fuel burn was 8 gph average and the totalizer was 4 gallons more than actual. The first 80 hours on plane the fuel flow and totalizer was perfect every fill up. Has anyone else had these problems and is replacing the red cube my only cure? The pic below is how I have it mounted.
