Its also used on GV engines, and it is a simple vacuum operated pressure 
regulator, same as turbo bypass valve, but instead of releasing pressure 
into turbo inlet, it releases it into IM. Nothing to do with  emission 
or fuel control. The fuel control is strictly via FP, check valve, 
thermo time switch, system pressure reg. and WUR As on any CIS, fuel 
gauge kit is a must. Have a look here:
