The Flow & speed sensor Photos I have posted ,are being used with the mpguino currently,my old zemco was retired when I bought the mpguino .
As for vapour separators ,I used one from a 70's 430 mercury wagon ,it worked ok but the zemco flow sensor could have been though out better ,the optical sensor is just too sensitive .
Later today ,I will post the circuit for the speed /flow sensor here.It's relatively simple so everyone should be able to coble one together.
