Delphi Fuel Injection Pressure Regulator P/N:FP10494
Delphi FP10558 fuel injection pressure regulator for the 2001-2002 Kia Rio 4-cylinder 1.5L and the 2003-2005 Rio 4-cylinder 1.6L keeps the fuel pressure steady at the injectors. It regulates the pressure of the fuel supplied to the fuel injection system.
Hard starting, rough running or poor drivability can be signs of a regulator that no longer holds pressure. A weak fuel pump, a clogged fuel filter or a leaking injector can be behind the same symptoms, so find the cause before you buy.
This regulator fits the 2001-2002 Kia Rio 4-cylinder 1.5L and the 2003-2005 Rio 4-cylinder 1.6L. Both take one regulator.

What symptoms can a failing fuel injection pressure regulator cause?
Hard starting, rough running or poorer drivability can be among the signs. A shop can test fuel pressure, since doing so means opening the fuel system.
Does 158-0716 interchange with the Delphi FP10558?
Yes. 158-0716 is one of the numbers Delphi FP10558 replaces, along with 800-452 and 5G1214.
