Continental 5/16 in Fuel Hose, 25 ft — Black SAE J30R7, 50 psi multipurpose

Continental 65127 is a 25-foot multipurpose fuel hose with a 5/16" inner diameter, rated for 50 psi working pressure and built for gasoline, diesel and ethanol blends.

This Continental Elite SAE J30R7 hose is engineered for fuel lines, PCV and emission-control connections, or fuel return lines where low- to moderate-pressure service is required. Constructed with a black nitrile tube, two-spiral synthetic reinforcement and a chlorinated polyethylene cover, it balances flexibility, chemical resistance and heat tolerance. It is precision-tested in the U.S.A. and designed to maintain full flow while resisting ethanol, sour gas and typical under-hood conditions.

What fuels and fluids can I use with this hose?

The 65127 is compatible with unleaded gasoline, diesel, gasoline-ethanol blends up to E10, E85 and sour gas. Its nitrile tube and CPE cover provide resistance to common fuels and ethanol-related swelling, making it suitable for many automotive and small-engine fuel applications.

• Unleaded gasoline and diesel
• Gasoline blends up to E10 and E85
• Sour gas compatibility for certain environments
• Not intended for high-pressure fuel-injection lines

How durable and heat-resistant is the Continental 65127?

Built for durability, the hose uses 2-spiral synthetic reinforcement for burst strength while the CPE cover resists abrasion and heat. It performs across a wide temperature range and is specified to retain integrity under typical engine-bay conditions.

• Working pressure: 50 psi; burst pressure: 250 psi
• Temperature range: -40°F to 257°F (-40°C to 125°C)
• Black nitrile tube for fuel resistance
• CPE cover for improved heat and abrasion resistance

Will the hose keep fuel flow consistent and safe?

The internal diameter and construction are selected to minimize flow restriction while resisting collapse and swelling from ethanol blends. Precision manufacturing helps ensure consistent inner diameter and reliable performance over the hose length.

• Inner diameter: 5/16" (.3125") for steady flow
• Outer diameter: .56" for common clamp compatibility
• Maintains full flow under recommended conditions
• Precision-tested for consistent dimensions and performance

Important: Do not use this hose for high-pressure fuel-injected systems. It is intended for low- to moderate-pressure fuel, PCV and emission-control applications only.

How long is the hose and where is it made?

The product ships as a 25-foot length suitable for repair shops, DIY projects, or fleet maintenance. Continental manufactures this Elite-series hose in the United States to SAE J30R7 standards.

• Length: 25 feet — ready for multiple cuts or long runs
• Made in U.S.A. by Continental Elite
• Constructed to SAE J30R7 specification
• Supplies enough material for several connections or a single long line

Who is this for? Technicians, mechanics and knowledgeable DIYers needing a reliable, ethanol-capable fuel hose for carbureted engines, fuel-return lines, PCV or emission-control connections will find the Continental 65127 a practical choice. If you require a hose for high-pressure, fuel-injected systems, select a purpose-built fuel-injection line instead.
