🔌 Function

The fuel pressure regulator maintains controlled fuel pressure at the injector rail, allowing the EFI system to meter fuel correctly under changing engine load and throttle conditions.

Common signs of failure:

• Hard starting or extended cranking

• Rich running or fuel smell

• Lean hesitation or bogging under throttle

• Rough idle

• Poor acceleration

• Fuel pressure outside specification during testing

📦 Condition

• Genuine used part

• Removed from running engine where applicable

• In good working condition unless otherwise stated
