Keep fuel pressure steady across the rail with the Standard Ignition fuel injection pressure regulator PR215. This regulator drops in as a direct-fit replacement for the listed applications, including the 1995-1998 SAAB 900, 1999-2003 SAAB 9-3, 1999-2009 SAAB 9-5, 1997-2001 Cadillac Catera and the 2001-2005 Saturn L300.
A fuel injection pressure regulator maintains the correct pressure differential between the fuel rail and intake manifold, routing excess fuel back to the tank so the injectors deliver a consistent, properly metered spray. When the original regulator fails, drivers often notice hard starting, rough idle, a fuel odor, or poor fuel economy — if a faulty pressure regulator is the cause, this unit replaces it.
- Regulated fuel delivery: holds proper rail pressure relative to manifold vacuum for accurate injector metering.
- Return-style operation: vents excess fuel back to the tank to stabilize pressure under changing load.
- Direct-fit replacement: designed for the listed SAAB, Cadillac and Saturn applications.
