TKKEUEP Gasoline Fuel Filler Neck Hose with Clamps
Features: Reinforced fuel filler hose with nylon inner cord for added strength; nitrile tube rated for -40°F to 212°F; length 15 7/8″ to fit typical tank-to-cap extensions; designed to accommodate standard 1 3/8″ ID fittings. Best for: vehicle fuel filler extensions and installations requiring a robust, long-lasting line. Limitation: verify fits with your specific tank and filler neck geometry before installation.
Polycarbonate Round Tube 1 1/2″ OD x 1 3/8″ ID
Features: Clear extruded polycarbonate tube with 1.5″ outer diameter and 1 3/8″ ID; available in multiple lengths (12″ to 72″). Best for: projects requiring rigid tubing with good visibility of contents and straightforward fittings. Limitation: polycarbonate is less flexible than rubber hoses and may not suit high-flex applications.
1.375 Inch Fill Hose for RV/Concession (5 ft)
Features: Flexible, non-kinking fill hose with 1 3/8″ ID; 5 ft length suitable for RV or concession systems. Best for: setups requiring a longer, flexible fill line without kinking. Limitation: verify chemical compatibility with fuels used and ensure proper clamp connections.
1 3/8″ ID Straight Gasoline Fuel Filler Neck Hose
Features: Straight configuration, 15 7/8″ length; reinforced with nylon cording; nitrile tube; -40°F to 212°F temperature range; EPA-compliant for fuel contact. Best for: replacement hoses requiring solid reinforcement and EPA compatibility. Caution: measure existing fittings to ensure proper ID and length before ordering.
1 3/8″ ID Gas Tank Filler Hose with Clamps
Features: 15-7/8″ long, straight hose with four clamps; reinforced nylon within to resist oil and fuel exposure; temperature range -40°F to 212°F; EPA-compliant. Best for: replacing a complete filler neck connection with included clamps for quick installation. Limitation: ensure compatibility with existing tank fill neck and filler cap recess.
Buying Guide
Key considerations when choosing a 1 3/8 inch ID pipe or hose:
- Material and compatibility: Fuel hoses typically use nitrile rubber with reinforcement for strength; polycarbonate tubes offer rigidity and visibility but less flexibility. Choose based on exposure to fuel formulations and required bending radius.
- Length and fittings: Measure the distance between the tank and the filler cap and verify end fittings. Longer lengths reduce kinking risk but may add unnecessary bulk in tight spaces.
- Temperature range and EPA compliance: Ensure the product supports the operating temperatures and meets fuel-contact standards for current gasoline formulations.
- Reinforcement and durability: Nylon cords inside hoses improve tensile strength and oil resistance; consider this for high-stress installations in engines or vehicles.
- Clamps and hardware: Some sets include clamps; factor in installation hardware to ensure a secure, leak-free connection.
- Visibility versus flexibility: Clear tubes aid inspection and alignment, while flexible hoses accommodate routing challenges; assess project needs accordingly.
FAQ
- What does 1 3/8″ ID mean?
It refers to the inner diameter of the hose or tube, which should match the outer diameter of the mating fittings or another hose with the appropriate ID. - Are these hoses suitable for vehicle fuel systems?
Several options are designed for gasoline with temperature resistance and EPA compatibility; always verify fit to your specific vehicle and fuel type. - Should I choose a reinforced hose or a clear polycarbonate tube?
Reinforced hoses are better for flexible routing and fuel exposure; clear polycarbonate is ideal for rigid, visible runs where bending is minimal. - Is a longer hose always better?
Longer hoses provide slack and easier routing but can increase potential leak points if not secured properly. Match length to application needs. - Do these products come with clamps?
Some sets include clamps; others require separate hardware. Check product details to confirm included components. - How do I verify the correct ID and length before ordering?
Measure the existing hose or pipe and compare with product specifications (ID and length) to ensure compatibility.
