Keep fuel delivery steady and your engine running the way it should with the Standard Ignition Fuel Injection Pressure Regulator PR543. It installs as a direct-fit replacement for the 2011 Kia Optima, 2012-2014 Hyundai Accent, 2012-2013 Hyundai Azera, 2012-2015 Hyundai Veloster, 2012-2014 Kia Rio, 2012-2019 Kia Soul, 2014 Kia Forte Koup and 2014-2015 Kia Optima.
- Regulates fuel pressure: maintains the pressure the injection system needs by controlling how much fuel returns from the rail.
- Supports consistent fuel delivery: helps keep injector supply pressure within the target range for proper fuel metering.
- Direct-fit replacement: made to replace the pressure regulator on the listed applications.
The fuel pressure regulator manages the pressure supplied to the fuel injectors, bleeding off excess fuel so the rail stays within its target range. Signs the regulator may need replacing include rough idle, hard starting, poor fuel economy or a fuel odor. Diagnose the cause first; if a failed pressure regulator is behind the symptom, PR543 replaces it.
