Fuel high pressure sensor Fuel pressure sensor transducer 0281006325 For CUMMINS DAF The fuel pressure sensor is installed at one end of the fuel rail to measure the fuel pressure in the common rail pipeline. It is a part of vehicle’s fuel system and designed to monitor the fuel pressure that is present at the fuel rail. The sensor sends this signal to the ECU, which then uses it to make adjustments to the vehicle’s fuel and timing. Common Rail Technology can greatly reduce the fuel supply pressure of diesel engine with the change of engine,so also reduce the defects of traditional diesel engine.
