Start engine and run at idle, pressure should be between 28-37 psi. ECU pressure sensor to provide high-pressure oil-track pressure signal; flow buffers (current limit) guarantee in a fuel injector leakage failure to cut off the supply to the injector, and reduce common-rail and high pressure in the pipeline the pressure fluctuations; pressure on the high-voltage limiter ensure that the oil pressure in the. The FPS sends an electrical signal to the ECM telling it what the engine fuel pressure is at any given speed. From China. When it comes to your Volvo V50, you want parts and products from only trusted brands. The high fuel pressures used in these systems also improve fuel atomization at the injector nozzle. Check that the pressure is within specs, and it doesn’t leakdown more than 5PSI within 60 seconds after pump shutdown.
