I heard of an HEV (Hybrid Electric Vehicle) team using compressed natural
gas (CNG) and I asked them specifically about the metering and pressure
regulating problem.  If I remember correctly they had a regulator at the
output of the CNG main tank (actually a pressure transducer and a solenoid
valve, but that may not be necessary) leading into a plenum or reserve
tank.  It simply opened and closed the valve to keep the desired pressure
in the plenum and injected off of there.  I know the engine runs so I guess
it worked.
