Hold rail pressure steady and keep fuel metering accurate with the Standard Ignition Fuel Injection Pressure Regulator PR115. A fuel pressure regulator maintains the specified pressure across the injectors and bleeds off excess fuel so the injectors deliver a consistent charge as engine load changes. It's a direct-fit replacement for the 1995-1997 Honda Accord (V6-2.7L), 1990-1991 Lexus ES250 (V6-2.5L), 1992-1993 Lexus ES300 (V6-3.0L), 1996-1997 Lexus LX450 (L6-4.5L), 1988-1991 Toyota Camry (V6-2.5L), 1992-1993 Toyota Camry (V6-3.0L), and 1993-1997 Toyota Land Cruiser (L6-4.5L) — see the Buyer's Guide tab for the full list.
- 45 psi operating pressure: regulates the gasoline fuel system to the rated set point.
- Angled nipple orientation for the fuel connection.
- Validation tested: 200+ hours of vibration testing plus 1,000+ hours of extreme heat-and-cold operational and on-vehicle testing.
- Corrosion-resistant, durable materials with connections sealed to resist leaks.
Ships with a caution sheet. Country of origin: Mexico. Signs the regulator may need replacing include rough idle, hard starting, poor fuel economy, or a fuel odor; because these can have other causes, diagnose the fuel system first — if a failed pressure regulator is the cause, the PR115 replaces it.
