I'm at the point on my B&S system to measure the flow rate of an injector I
acquired (don't recall the exact part number, but it's a Ford/Chrysler port 
injector) and develop the pulse width values for an open loop algorithm. 

Ballpark fuel flow rates for the B&S are from 2 lb/Hr idle to 5 lb/Hr WOT - If 
reducing the fuel rail pressure isn't enough to obtain reasonable pulse 
widths without compromising the injector spray pattern for a 1" intake port, 
then I have a problem too.
