Meonum Submersible Fuel Hose 5/16 inch 1FT 2-Pack – SAE J30R10 E85-Compatible In-Tank Hoses with Clamps

This kit delivers two short lengths of SAE J30R10-compliant in-tank hose plus four heavy-duty stainless-steel clamps for a straightforward replacement or prototype build. Constructed for submerged use, the hoses resist ethanol, gasoline, and diesel blends while maintaining dimensional stability under fuel-system conditions. Measurements and pressure ratings are included below to help you confirm fit and suitability for your application.

How durable are these hoses under in-tank conditions?

These hoses are engineered with a multi-layer structure to maintain integrity when submerged and subject to chemical exposure and pressure. The synthetic-rubber inner layer resists fuel breakdown, a braided reinforcement maintains shape under load, and an outer cover protects against abrasion and environmental exposure.

• SAE J30R10 design for in-tank service
• Working pressure: 300 PSI; burst rating: 1200 PSI
• Operating range: -40°F to 257°F (-40°C to 125°C)
• Minimum bend radius: 64 mm to avoid kinks

Will these hoses handle ethanol blends like E85?

Yes — the hose materials and construction are selected to tolerate ethanol-containing fuels without softening or swelling. That makes this set suitable for fuel systems using modern formulations, including high-ethanol blends, within the hose’s intended low-pressure zone inside tanks or modules.

• Fuel-compatible inner tube designed for ethanol resistance
• Tested for gasoline, diesel, and E85 compatibility
• Recommended for in-tank and low-pressure fuel-system use only

What are the exact dimensions and what’s included in the kit?

Each hose measures 5/16 inch (8 mm) internal diameter with an approximate 14 mm outer diameter and a one-foot length. The package contains two hoses and four stainless-steel clamps so you can secure both ends of each hose for a complete short-run installation.

• ID: 5/16" (8 mm); OD: 14 mm ±0.6 mm; length: 1 foot
• Two 1-foot hoses per pack and four heavy-duty stainless clamps
• Designed for in-tank connections like pump modules and sending units

How should I install and where should these hoses not be used?

Installation is straightforward: route with a minimum bend radius, secure clamps at fittings, and avoid chafing points. These hoses are not intended for downstream high-pressure fuel-system lines that operate beyond the low-pressure/in-tank environment.

• Use clamps supplied; tighten to appropriate torque for fittings
• Maintain 64 mm minimum bend radius to prevent flow restriction
• Do not use for external high-pressure fuel lines downstream of pumps

Who this kit is for: technicians, vehicle restorers, marine mechanics, hobbyists, and engineers who need short runs of reliable in-tank fuel hose for fuel pump modules, sending units, or prototype rigs. If you require a submersible, ethanol-resistant hose for low-pressure, in-tank service and want clamps included for immediate installation, this compact Meonum kit is a practical choice. For high-pressure external fuel lines, select an appropriate rated hose designed for that service instead.
