Delphi Fuel Injection Pressure Regulator P/N:FP10494
Delphi FP10544 fuel injection pressure regulator for the 1990-1993 Ford Festiva 4-cylinder 1.3L controls the fuel pressure in the injection system. This Delphi fuel injection pressure regulator keeps pressure consistent and predictable across its range of control, which supports drivability.
Hard starting, a rough idle or poor fuel economy can mean this regulator is worn, though a weak fuel pump or a clogged fuel filter can be behind the same signs.
This regulator fits the 1990-1993 Ford Festiva with the L4-1.3L engine, and each car takes one.
