Craig, we tested the Rochester units for the 4-cyl Multec/TBI (OPEL) with an actuator box.
You should be able to make it yourself. Do multiple shots for more accuracy.

Later I changed the layout and used a TBI with pressurized fuel.
You want to make sure they operate properly under higher pressure (above the designed value of 3(?)bar. I forgot, used to write the trouble shooting manuals until 1995.

Rochester back then (1989+) supplied a fancy fuel replacement liquid.

You know that there is a limit to opening time (total) and minimum. They do need to ramp up and close too. The danger is that at idle with higher pressure you may run rich.
