How much is to replace a fuel pressure regulator? on 1997 Ford Contour

Every time I was starting my engine, the motor would not run unless I would press the gas pedal. Sometimes I would have to keep the gas pedal pressed longer to keep the motor running. In the beginning of this issue this would happen at random. At the repair shop they told me they could not diagnose unless the car would not be running at all. I had to wait longer until this issued worsened and finally it was discovered the fuel pressure regulator was leaking and I had to also replace the main belt because it was kind of shot (they said). Thank you for your kindness in answering my question.

Figure $260 parts and labor for a reasonable estimate. 1.4 hours, about $110 for the part.
