Hold fuel pressure steady across every injector with the Standard Ignition Fuel Injection Pressure Regulator PR313. A fuel pressure regulator controls the pressure differential across the fuel injectors and returns excess fuel to the tank, so the injectors receive a consistent supply. It drops in as a direct-fit replacement for the 1999-2002 Daewoo Leganza (L4-2.2L), 1999-2002 Daewoo Nubira (L4-2.0L), 1998-2000 Isuzu Amigo (L4-2.2L), 1998-2003 Isuzu Rodeo (L4-2.2L), and 2001-2003 Isuzu Rodeo Sport (L4-2.2L).
If a failed pressure regulator is the cause of hard starting, rough running, a fuel odor, or poor fuel economy, this unit replaces the original to restore proper regulation. Diagnose the underlying cause before replacing, as these symptoms can have other sources.
