I sold about 35 of those back in about 1982, for $175 canadian each. I
still have one of the fuel flow sensors, as well as the hand-held
tester/diagnostic unit.
There was a unit made that measured the injector pulse width to replace
the flow unit on EFI.
>From what I remember it reset after every so long - say 1 second - of
injector opening, and sent a pulse to the computer the same as the flow
sensor did. You calibrate the unit - basically so many pulses to the
gallon. This module was available from Compu-cruise at the time, along
with the "electronic clutch switch" which detected excessive engine
acceleration and shut off the cruise (if you pushed the clutch, or put
the tranny in neutral, or broke a driveshaft, etc. etc.

By the way, the units were EXCELLENT.

If you want the diagnostic unit (cost me $145 or thereabouts back then)
$25 US plus shipping and it's yours. The spare fuel sensor will go for
$35 US plus shipping.
