Let's pick that figure of 3% and do the calculation. Average owner-flown
aircraft is something on the order of 130 hours a year. Just for grins,
let's pick a round number of 10 gallons per hour at the national average
(right now) of $3.35 a gallon. That's $4355 of fuel a year. Times 0.03 is
around $130 a year. I doubt it will be decades.

Let's say that having the fuel flow meter allows you to improve your
fuel burn by 3% overall... How many decades is that to generate a net
return on the cost for the flow meters?
