Fuel Line 7/8ft ID NBR Hose 5 ft - Fuel Injection Compatible

In this review the Fuel Line 7/8' ID NBR Hose is assessed as a basic, serviceable replacement hose for small engines and fuel-injected systems. The bottom line: it is best for DIY mechanics and fleet maintenance needing a heavy-duty, 5 ft length hose that handles gasoline, E-85, diesel and lubricants; the single biggest reason to buy is its combination of a true 7/8' inner diameter with an oil- and ethanol-tolerant NBR liner rated to 300 PSI working pressure, which covers many common automotive and small-engine applications.

Key Features

• 7/8' inner diameter: Provides a consistent fit for hoses and fittings that require a 22 mm internal bore, useful when replacing worn fuel lines.
• 1.23' outer diameter: The 31 mm OD gives predictable clamp engagement and compatibility with hose barbs and clamps on most small fuel systems.
• NBR liner: Nitrile butadiene rubber offers oil resistance and ethanol tolerance so the hose resists degradation from gasoline, E-85 and diesel.
• Temperature range: Rated from -40 to +275 degrees F, allowing use across cold starts and high under-hood temperatures.
• Pressure ratings: A working pressure of 2 MPa (300 PSI) and a higher burst margin support fuel transfer and return lines in many service scenarios.
• 5 ft length: Long enough for routing runs on small engines, motorcycles, ATVs and many automotive repairs without immediate splicing.

Who It's For

The hose is aimed at DIY mechanics, small repair shops and fleet technicians who need a robust, ethanol-tolerant replacement fuel line for cars, trucks, buses or small engines and who plan to install with hose barbs and clamps. Its size and NBR construction suit fuel-injected systems and vapor or vacuum smog control lines where oil and ethanol resistance matter.

It is less suitable for high-end motorsport applications that demand braided stainless lines or for users who require pre-fitted ends; anyone needing longer runs or a different inner diameter should look for an alternate size rather than attempting risky adapters.

Pros & Cons

Pros

• Durable NBR construction that resists oils and ethanol for extended service life in many environments.
• Clear dimensional fit with 7/8' ID and 1.23' OD for reliable clamp and barb sealing.
• Good operating envelope with -40 to +275 degrees F and a 300 PSI working pressure for typical fuel system needs.
• Handy 5 ft length that reduces the need for joins on common routes.

Cons

• Some customers report occasional sizing or leakage issues, so careful measuring and proper clamps are required during installation.
• Not intended as a crimped or pre-assembled hose; requires separate barbs and clamps for a secure connection.

Frequently Asked Questions

Can this hose handle E-85 fuel?
Yes, the NBR construction is ethanol tolerant and is specified for gasoline and E-85 use.

Does it come with hose ends or clamps?
No, the product is a push-on NBR hose and requires separate hose barbs and clamps for proper installation.

Is this suitable for high-pressure fuel injection lines?
It is designed for fuel-injected system use with a 300 PSI working pressure, but users should confirm pressure demands of their specific injection system before fitting.
