Buying Guide
Key purchase considerations to compare:
- Hose size compatibility: Most marine fittings specify 5/16″ (8mm) or 1/4″ (6mm) I.D. Ensure your hose matches the fitting size.
- Engine compatibility: Check which brands the fitting supports (Mercury, Mariner, Force, Yamaha) to avoid mismatches.
- Connection type: Quick-disconnect systems can be barrel, clip-on, or barb-style. Choose based on how you plan to disconnect (tank end vs engine end).
- Seal design: Double-seal fittings reduce leaks, but installation must be exact with proper clamps.
- Replacement scope: Some kits include mating connectors and clamps; others are just the connecting piece. Decide if you need a full kit.
- Material: Brass fittings resist corrosion; ensure compatible with your fuel line material and environment.
