Reminder

Inspect your marine fuel lines annually and replace them every 3–5 years or at the first sign of soft spots, cracking, or fuel odor. Always use USCG Type A1 or A2 hose for compliance and safety.

Choosing the Right Marine Fuel Hose & Fittings

  • Hose Type: Type A1 for inboard systems; Type A2 for outboard or portable tanks.
  • Fuel Compatibility: Ensure ethanol-safe materials to prevent degradation.
  • Connections: Match your fittings to the engine brand (Yamaha, Mercury, Honda, etc.).
  • Installation: Secure with marine-grade clamps—avoid over-tightening.

Pro Tip

When replacing hoses, mark the fuel flow direction and prefill new primer bulbs to reduce startup time. Always double-check clamp tightness after your first engine run of the season.
