NOTETOUPT Fuel Line Assembly 5/16" 8mm Fuel Gas Line Hose

NOTETOUPT 5/16" (8mm) fuel line assembly with primer bulb and stainless-steel clamps is a ready-to-install 6-foot marine/RV fuel hose designed to deliver reliable fuel flow for compatible outboard motors and portable fuel tanks.

This complete fuel hose kit combines an ethanol-resistant rubber line, a high-flow primer bulb and corrosion-resistant steel clamps for a durable, leak-resistant connection. Built for boats, trailers and recreational vehicles, the assembly is sized to the common 5/16" (8mm) fittings and supplied at a 6-foot length to cover most portable tank and engine linkups. The kit is new, black in color and intended as a universal replacement for many non-Suzuki and non-Mercury outboard setups.

How does this fuel line improve fuel delivery on my outboard or RV?

The rubber primer bulb is shaped and positioned to boost fuel movement from a portable tank to the engine, reducing the time it takes to prime. The hose material is designed to resist alcohol-blended fuels common today, keeping flexibility and preventing early hardening.

• High-flow primer bulb for faster priming and smoother starts
• Ethanol-resistant rubber maintains flexibility and longevity
• 6-foot length lets you route between tank and engine without extensions
• Steel clamps secure fittings to reduce leaks under vibration

Will this fit my engine and fuel tank connections?

The assembly uses a universal 5/16" (8mm) hose diameter that fits many portable fuel tanks and outboard engine fittings, including Johnson outboards. It is not suitable for Suzuki or Mercury models that require manufacturer-specific fittings or other diameters.

• Standard 5/16" (8mm) hose size for broad compatibility
• Includes clamps to adapt to standard barb fittings
• Not compatible with Suzuki and Mercury proprietary connectors
• Ideal replacement for Johnson and many generic outboard setups

What materials and durability features does this assembly include?

The hose and primer bulb are made from rubber compounds formulated to resist degradation from ethanol-blended gasoline. Steel hose clamps are provided to resist corrosion and create tight seals; together they extend the service life compared with untreated fittings.

• Alcohol-resistant rubber construction to slow material breakdown
• Stainless-steel hose clamps for corrosion resistance and strength
• Black finish hides wear and resists UV fading when properly stored
• Recommended storage away from direct sunlight and high heat

How do I install and maintain the NOTETOUPT fuel line assembly?

Installation is straightforward: slip the hose onto the fuel barb, position the primer bulb where it won’t kink, and tighten the stainless clamps. Regular checks for cracks, firmness of the bulb and clamp tension will keep the assembly performing well and help prevent leaks.

• Slide hose ends fully onto barbs, then tighten clamps securely
• Place primer bulb in an accessible, kink-free position
• Inspect hose and bulb periodically for hardening or splits
• Store indoors away from direct sunlight to prolong life

Who is this for? This NOTETOUPT 5/16" fuel line assembly is aimed at boat owners, RV users and anyone needing a robust, universal fuel transfer connection for compatible outboard motors and portable tanks. Choose this kit if you want a ready-made 6-foot hose with a high-flow primer bulb and corrosion-resistant clamps for dependable fuel delivery. Do not use it on Suzuki or Mercury engines that require model-specific fuel lines; otherwise it’s a practical replacement or spare for Johnson outboards, small utility engines and many recreational fuel setups.
