attwood Marine Fuel Line Kit for Mercury — 6 ft 3/8 in with Sprayless Connector & Low-Permeation Primer Bulb

This kit is engineered for modern boating needs: it fits Mercury outboard engines (1998 and newer), meets strict low-permeation standards, and is optimized for ethanol-blended fuels. The assembly pairs Attwood’s award-winning Universal Sprayless Connector with a multi-layer primer bulb and fiber-reinforced hose, delivering faster priming, reduced evaporation, and increased resistance to kinking, hardening, and leaks. Materials and fittings are selected to withstand marine conditions so you get dependable performance season after season.

How does the sprayless connector improve safety and convenience?

The Universal Sprayless Connector is designed to eliminate the plume of pressurized fuel that can appear when attaching or detaching a hose from the tank. That reduces spills and exposure to fuel while making hookups quicker and less messy. It’s a significant upgrade for anglers and recreational boaters who frequently connect and disconnect fuel lines on the water.

• Push-to-connect design limits fuel spray during hookup and removal
• Compatible with standard Mercury tank fittings for effortless mating
• Durable construction withstands repeated use without performance loss

What makes the primer bulb and hose suitable for ethanol fuels and changing temperatures?

The multi-layer primer bulb uses a low-permeation construction to reduce vapor loss and is rated to deliver noticeably more fuel per pump than many competitors. The fiber-reinforced hose resists kinking and hardening even when exposed to temperature swings and ethanol blends, helping ensure consistent flow and easier starting regardless of conditions.

• Low-permeation bulb reduces evaporation and retains more fuel
• Higher output bulb primes quickly in cold and warm climates
• Reinforced hose resists kinks and maintains flexibility over time

Are the fittings and clamps built for long-term marine use?

This kit uses corrosion-resistant fittings and 360-degree stainless steel clamps to secure connections and resist the saltwater environment. Those choices lower the chance of leaks and the need for frequent replacement, so you spend more time on the water and less time performing maintenance.

• Stainless clamps provide full 360-degree compression for secure seals
• Corrosion-resistant fittings extend service life near saltwater
• Engineered to mate with the 8897-6 engine fitting commonly found on Mercury outboards

How easy is the kit to install and where does it fit best?

Installation is straightforward for anyone familiar with portable fuel line setups: connect the sprayless connector to the tank fitting, attach the primer bulb inline, and secure the hose to the engine end. The 6-foot length and 3/8-inch ID suit most small to medium outboards and portable fuel tanks used for fishing boats, runabouts, and other recreational craft.

• Pre-assembled 6-foot hose simplifies replacement or upgrade
• 3/8-inch internal diameter matches common Mercury engine fittings
• Works with portable tanks and Mercury outboards manufactured 1998 and later

Who is this for? Boaters who want a trustworthy fuel connection that reduces spills, primes faster, and tolerates ethanol blends will benefit from the Attwood 93806MUS7 kit. It’s ideal for anglers, weekend boaters, and owners of Mercury outboards seeking an OEM-compatible replacement or an upgrade to a safer, low-permeation fuel line. If you prioritize minimized vapor loss, corrosion-resistant hardware, and reliable priming across temperature ranges, this assembly delivers marine-grade performance with easy installation and long-term durability.
