attwood Yamaha fuel line kit — 3/8 in x 1.8 m, low-permeation hose with primer bulb

The Attwood 93806YLP7 is a complete 6‑foot, 3/8" low‑permeation fuel line kit built for Yamaha outboards, with primer bulb and precision fittings for reliable fuel delivery and reduced vapor loss.

This marine fuel line assembly combines a reinforced, EPA‑compliant hose, Attwood’s low‑permeation connector technology, and a multi‑layer primer bulb engineered to withstand ethanol blends and harsh saltwater conditions. The kit is assembled in the USA using marine‑grade materials chosen to resist cracking, kinking, and degradation from heat and vibration. It’s intended as a direct replacement or fresh installation for Yamaha engine applications that require a 3/8" feed line and dependable priming performance.

How does this kit keep fuel vapor and emissions down?

Attwood uses low‑permeation inner layers and a multi‑layer hose construction to limit fuel vapor migration and meet EPA and CARB requirements. That design reduces evaporative emissions and helps minimize fuel odors in the boat cabin or engine bay.

• Low‑permeation tubing formulated to reduce vapor loss
• Assembled in the USA to EPA/CARB standards
• Reinforced jacket to prevent micro‑cracking that increases emissions

Will this kit handle ethanol‑blended gasoline and marine conditions?

The hose and primer bulb materials are chosen specifically for ethanol resistance, avoiding inner‑layer delamination common with inferior products. Corrosion‑resistant fittings and robust construction make the kit suitable for saltwater, high heat, and vibration‑intensive environments.

• Ethanol‑resistant inner layers protect against fuel breakdown
• Marine‑grade primer bulb engineered for consistent priming after storage
• Stainless steel clamps and molded hose barbs for secure, leak‑resistant joints

How does the primer bulb and connector arrangement improve starting?

The multi‑layer primer bulb provides quick, consistent fuel delivery to the engine, reducing cranking time and making restarts after storage easier. Precision‑molded fittings and Attwood’s Universal Low‑Permeation connector ensure a tight, sprayless connection to Yamaha engine fittings for dependable flow.

• Quick‑action primer bulb reduces air pockets in the fuel line
• Precision molded hose fittings for smooth fuel flow
• Matched to Yamaha engine fittings for a secure interface

What installation and compatibility details should I know?

The kit includes a 6 ft. length of 3/8" Type B1 fuel hose, a multi‑layer primer bulb, and the female 8896LP6 hose tank fitting for Yamaha engines. It was designed for ease of installation: use the supplied hose barbs and stainless clamps to create leak‑free connections; note that the male Universal Sprayless Connector (USC) tank fitting is not included.

• 6 feet long, 3/8" diameter Type B1 fuel hose included
• Female 8896LP6 hose tank fitting provided; male USC tank fitting sold separately
• Stainless clamps and molded barbs for secure assembly

Who is this for? The Attwood 93806YLP7 is aimed at boat owners, marine mechanics, and DIYers who operate Yamaha outboards and want an OEM‑style fuel line that meets EPA/CARB standards, resists ethanol damage, and delivers reliable priming and fuel flow. It’s a practical choice for routine replacements, winter‑storage recommissioning, or any installation where reduced vapor emissions and long‑term durability are priorities.
