If your car has digital injectors . . .

Also, would a meter right after the fuel pump suffice, or should I attach it somewhere else like the injectors for a more accurate reading (e.g. to account for things like fuel return, which I do not know if my car has)?

Thanks!
. . . just use the arduino to tally the total time the injectors are open. You can then equate this to a volume flow of fuel for a unit time - assuming constant rail pressure.
