Gilles & all
I'm not familiar with 914 but I do remember that the return flow from 
the regulator must be unrestricted otherwise the back pressure will 
cause rich mixture? Because of the high flow rate required with all 
pumps running the return pipe needs to be at least -6 size.
Hope I'm not confusing the issue
