Detailed Description

The Standard Ignition PR455 is a fuel injection pressure regulator designed to manage fuel pressure within the injection system. Its steel construction and silver finish provide a durable OE-style replacement solution, while the fixed, non-adjustable design matches applications that require direct pressure regulation rather than tuning. For Subaru Forester and Subaru Impreza fuel system service, PR455 offers a direct-fit replacement path for vehicles listed in the fitment data.

Use this regulator when servicing fuel delivery concerns on 2006-2010 Subaru Forester and 2002-2008 Subaru Impreza models. The Standard Ignition PR455 is also referenced by DNJ PR455, Gates 24163, and OE-style numbers 2-199023 and 22670AA251.

What It Helps Address

• Fuel pressure that is outside the expected range
• Hard starting related to unstable fuel delivery
• Rough idle caused by pressure regulation issues
• Fuel system performance problems tied to a worn regulator
• Replacement needs during Subaru fuel injection repair

Installation Notes and Tips

• Verify the vehicle year, make, and model before ordering.
• Confirm the existing regulator uses a bolt-mount layout with a straight nipple orientation.
• Inspect fuel lines, seals, and surrounding components during replacement.
• Follow the included caution sheet and service procedures for the fuel system.
• Relieve fuel system pressure before removing the old regulator.

Quality Assurance

Standard Ignition supplies this PR455 regulator as a new replacement component for fuel injection service. Its steel construction, OE-style mounting, and application-specific fitment support consistent repair work on listed Subaru models.
