307 antipollution

Mrb arkdslar have a question for you: I wonder if the rail operator and the fuel pressure regulator are the same? I would be glad if arkds with knowledge comment;)

There's some confusion here. Fuel pressure regulator is a part on the rail road, but I could not understand what is the caste from the rail operator.

Brother Koliva last year, my 307 vehicle did not give an error of antipollution fault.

rail sender is on the ramp leading to the injectors. the fuel pressure regulator is on the fuel pump.
