The control unit, water level sensing, boost switching and possible 2 stage jetting is easy for me to sort out (once I figure out the sizes of jets to use), but I'm wondering if the system would still work with a fuel pump? The system is for a 306 Turbo Diesel which will eventually be running about 18-20 PSI of boost and I'm looking to cobble up an equivalent to the 1S system, but with water level sensing and boost cutting (back to 14-15PSI) in the event of water outages.
PS. The system will be running 12.5% meth/water max (as recommended for diesel by Richard L), would the pump handle this?
Thanks

I wouldn't recommend you to use a fuel pump for water or water/methanol mix. One part inside the fuel pump is a motor, made up with iron. The water will attack the iron and form rust. I also think the bearings are iron based.
YOu can get yourself a shourflo or flojet pump, they are relatively low cost.
