Delphi Fuel Injection Pressure Regulator P/N:FP10394
Delphi FP10686 fuel injection pressure regulator for the 2011-2015 Hyundai Sonata 4-cylinder 2.4L and other vehicles controls the fuel pressure in the injection system. This Delphi fuel injection pressure regulator is tested with OE engineering.
Hard starting, rough running or a fuel smell can mean the regulator is failing, but those signs also come from other fuel-system parts. Before replacing it, look the regulator over with the engine off and cool for fuel seepage, and leave a fuel pressure test to a shop.
The list also includes the 2011-2016 Kia Optima 4-cylinder 2.4L and the 2010-2013 Kia Soul, and each takes a single regulator. For any other car, open the "Vehicles it fits" section and look up your exact model and engine.
