attwood Marine Fuel Line Kit 5/16 in x 6 ft — EPA-Compliant Low-Permeation Hose with Primer Bulb

The Attwood 951606ULP7 is a ready-to-install, EPA-compliant marine fuel line kit with a 6-foot, 5/16-inch low-permeation hose and a multi-layer primer bulb for reliable outboard fuel delivery.

This kit combines a reinforced, low-permeation fuel hose and an advanced primer bulb to reduce vapor loss while delivering consistent fuel flow to outboard engines. Built to resist ethanol blends, saltwater corrosion, kinking and heat, the assembly is designed for both replacement and new installations. All components are manufactured to meet strict environmental standards and provide long-term durability under marine conditions.

How does this kit reduce fuel vapour and meet environmental rules?

The hose and connectors use low-permeation materials that limit fuel vapour escape and comply with EPA (and CARB where applicable) standards. Using a low-permeation assembly helps reduce odour, evaporation losses and the environmental footprint of your boat’s fuel system.

• Low-permeation construction reduces hydrocarbon emissions
• Assembled in the USA to meet EPA and CARB requirements
• Reinforced hose discourages micro-cracking that increases permeability over time

Will it work with ethanol-blended fuels and harsh marine conditions?

Yes — materials selected for the hose and primer bulb resist ethanol-related degradation and remain flexible in a range of temperatures. Corrosion-resistant clamps and precision hose barbs help maintain leak-free connections even with vibration, salt spray and extended storage.

• Ethanol-resistant inner layers prevent delamination
• Reinforced exterior resists kinks, hardening and heat damage
• Marine-grade components tolerate saltwater and vibration

How easy is it to install and prime my outboard engine?

The kit arrives with a ready-cut 6-foot, 5/16-inch hose and a multi-layer primer bulb that makes manual priming fast and dependable. Installation requires adding the correct tank and engine fittings for your setup; once connected, the primer bulb accelerates fuel delivery and helps ensure quick starts.

• Simple cut-to-fit hose for custom installations
• Advanced primer bulb provides strong, consistent suction
• Precision hose barbs and stainless clamps promote leak-free joins

What fittings or accessories do I still need?

This universal kit includes the hose and primer bulb but does not include tank or engine fittings, so you’ll need the appropriate connectors for your tank and outboard model. Choice of fittings depends on your tank outlet size and the engine’s inlet; selecting compatible low-permeation fittings preserves the kit’s environmental performance.

• Purchase tank and engine fittings sized to your boat and motor
• Use corrosion-resistant clamps to maintain secure seals
• Confirm inlet/outlet diameters before final assembly

Who is this for? The Attwood 951606ULP7 fuel line kit is ideal for recreational boaters, small charter operators and marine technicians seeking an EPA-compliant, ethanol-resistant fuel connection for outboard engines. It suits anyone replacing an aging fuel line, installing a new tank-to-engine run, or upgrading to low-permeation components to meet environmental standards while ensuring dependable starts and steady fuel flow on the water.
