01
Represented the common rail as a vessel_h equipment node with a pressure control loop (PT/PIC) returning excess fuel to tank.
02
Used pump_pd for the high-pressure pump and pump_centrifugal for the lift pump to match positive displacement vs centrifugal head behavior.
03
Included a pressure relief valve in parallel with the control valve for rail overpressure protection.
Use when designing or documenting fuel delivery, return, and rail pressure control for common rail diesel vehicles or stationary engines.
