Delphi Fuel Injection Pressure Regulator P/N:FP10494
Delphi FP10421 fuel injection pressure regulator for the 1995-1999 Hyundai Accent 4-cylinder 1.5L holds fuel pressure steady for the injectors. This Delphi fuel injection pressure regulator controls the pressure the engine's fuel system delivers as engine demand changes.
Hard starting, a rough idle or poor fuel economy can mean the regulator's diaphragm is worn, though a weak fuel pump or a clogged fuel filter can produce the same signs, so find the cause before replacing the regulator.
It fits the 1995-1999 Hyundai Accent 4-cylinder 1.5L, which takes one regulator.
