Delphi Fuel Injection Pressure Regulator P/N:FP10056
Delphi FP10394 fuel injection pressure regulator for the 2000-2001 Mazda MPV and other vehicles regulates fuel pressure in the injection system. A regulator of this type keeps fuel pressure at the injectors at a set level.
A rough idle, hard starting or poor drivability can mean the regulator is worn, though a weak fuel pump or a clogged fuel filter can be behind them too, so rule those out first. This listing is one regulator, and the fitment lists one per vehicle.
This fuel injection pressure regulator is a direct-fit replacement for the 2000-2001 Mazda MPV, the 1998-2000 Ford Contour V6 2.5L and the 1998-2000 Mercury Mystique V6 2.5L. If your car isn't one of these, look it up by year and engine in the "Vehicles it fits" section.
