Fuel Pressure Regulation Caravan 3.0 L engine
One emissions schematic for the 3.0L engine suggests a "fuel pressure regulator" beneath
the intake plenum by the fuel injector rails. Never having looked I don't know and cannot see what's there without taking the plenum off etc. Isn't fuel pressure generated (and regulated) at the fuel pump in the fuel tank or is there some added regulator function at the engine? Thanks in Advance.
