Outus 2″ ID x 36″ Fuel Filler Hose
Best for: automotive and marine fuel connections requiring a strong safety margin. The hose is pressure-rated for fueling applications with a 135 psi working pressure and a 435 psi burst pressure, offering robust protection against fuel leaks during fueling. The nitrile rubber construction handles gasoline, ethanol, diesel, and biodiesel, reducing the risk of swelling or premature wear.
- Wide temperature range: -40°C to 100°C (-40°F to 200°F) for consistent performance in cold mornings and hot engine bays.
- Long length: 36 inches with a 2 inch inner diameter and 65 mm outer diameter for easy routing.
- Best for: users needing a high-strength, multi-fuel compatible hose with reliable performance under varying temperatures.
Caution: Verify connector compatibility with your vehicle or marine filler neck before installation to avoid fitment issues. Not designed for high-pressure fuel injection lines beyond its rated working pressure.
JROTTEMO 2″ ID Gasoline Fuel Filler Neck Hose
Best for: setups needing a straightforward, straight 15 7/8″ extension with included clamps. This hose is packaged with four clamps and a long enough length to connect between a tank and filler cap.

Buying Guide: Key Considerations For 2 Inch Fuel Filler Hoses
- Material composition: Look for nitrile (NBR) tubes with nylon reinforcement for durability and fuel compatibility.
- Pressure and temperature ratings: Higher working pressure and a broad temperature range improve safety and reliability across climates and fuel types.
- Length and diameter fit: Confirm the inner diameter (2″) and overall length to fit between your tank and filler cap without kinking.
- Reinforcement: Nylon or braided reinforcements reduce elongation and wear under pressure, useful for longer routing.
- Clamps and hardware: Some sets include hose clamps; verify if clamps are included and suitable for your clamps size and style.
- EPA compliance: If using in modern vehicles with strict fuel-contact standards, ensure the hose meets applicable EPA guidelines.
- Installation environment: Consider exposure to extreme temperatures, vibration, or marine settings where UV exposure and salt could affect hoses.
- Replacement compatibility: If replacing an existing hose, match measurements exactly to maintain proper fuel routing and cap seating.
Frequently Asked Questions
- What does 2″ ID indicate?
It means the hose inner diameter is two inches, which should match the opening of your filler neck and cap hardware for proper fit.
- Are these hoses suitable for diesel or biodiesel blends?
Many listed hoses are rated for multiple fuels, including gasoline, ethanol blends, diesel, and biodiesel, but always check the specific material and compatibility for your fuel type.
- Do I need clamps with a new filler neck hose?
Yes, most packages include clamps, and secure clamps help prevent leaks at the connection points.
- What should I measure before buying?
Measure the existing filler neck length, diameter, and the distance to the cap. Confirm the hose length, ID, and whether the extension is straight or angled to fit your setup.
- Is EPA compliance required for all filler hoses?
EPA guidelines apply to fuel-contact components in many contexts; verify that the hose meets relevant standards for your application.
