For all you 2001 XC70/V70XC owners, the Fuel Pressure Sensor does NOT exist.
I visited the Volvo dealer in town who later called their main Volvo place in lower 48,
and was confirmed. I also called the tech department of the VolvoUS and I was also
informed that my year does not have it and it is a mistake by them with the parts/repair
catalogs. The FPS started with some 2002 models.
