Yamaha - Pressure Regulator - Fuel System Component - 6P2-13906-00-00

Overview

Fuel pressure is one of those things you don’t see, but you definitely feel when it’s off. I’ve worked on engines that surged, idled rough, or just wouldn’t run clean, and it traced back to inconsistent pressure. When the regulator is doing its job, everything smooths out and the engine responds the way it should. It’s a small part that keeps the whole fuel system balanced.

Key Features

• Consistent Fuel Pressure Control – Maintains proper pressure for stable engine performance.
• OEM Precision Fit – Built to Yamaha specifications for correct operation and installation.
• Supports Efficient Combustion – Helps ensure the right fuel delivery across all throttle ranges.
• Durable Marine Construction – Designed to handle fuel exposure, heat, and vibration.

Engine & Boat Compatibility

Designed for Yamaha outboard engines equipped with fuel injection systems. Commonly used across a range of Yamaha outboards where proper fuel pressure is critical for smooth and reliable performance.
