Aftermarket trip computer for OBD1???

[Vettepilot]

Fixing up/restoring a 1994 GMC K1500.

I absolutely love trip computers for monitoring fuel mileage and averages and other trip info. I know it was done and offered on OBD1 computer systems because my 1987 Vette has it.

I have been searching and searching though, and cannot find a Trip Computer to add to my 1994 OBD1 GMC pickup.

Help anyone???

Thanks,

What fuel system did the Corvette use? How did it compute or track fuel used? I have three trip computers with fuel flow meter. The problem is TBI has the regulator and return within the throttle body. Therefore how do you account for fuel returned to tank?
I have thought about ways to engineer around it, but not fabricated anything yet.
