Mercury / Mariner 3/8" Fuel Line Assembly

Waveline Premium Viton Series - MPN: WL-3174

Upgrade your marine fuel system with the Waveline WL-3174 fuel line assembly, specifically designed for Mercury and Mariner outboard engines. This high-performance kit features a 3/8" (9.5mm) internal diameter, providing superior fuel flow compared to standard 5/16" lines, making it essential for engines 40hp and above to prevent lean-running conditions.

ETHANOL READY: Equipped with a premium primer bulb featuring Viton internal valves. Unlike standard rubber, Viton is highly resistant to chemical degradation from modern ethanol-blended fuels (E10), preventing the bulb from hardening or losing prime over time.

Key Features

  • Complete Assembly: Includes hose, bulb, and connectors.
  • UV Stabilized: Grey hose resists sun damage and heat absorption.
  • Anti-Kink Design: Braided reinforced lining for consistent flow.
  • Stainless Clamps: Marine-grade stepless ear clamps for leak-proof seals.
