Special tools and workshop equipment required

The Fuel Pressure Regulator Valve -N276- -1- is located in the right rail (cylinder bank 1) and maintains a constant pressure inside the rail and in the injector lines (fuel high pressure circuit).
If the pressure in the fuel high pressure circuit is too high, the regulator valve will open so that some of the fuel flows from the fuel rail back into the fuel tank via a return line.
If the pressure is too low, then the check valve closes and seals off the high pressure side from the low pressure side.
The Fuel Pressure Regulator Valve -N276- cannot be used again.
