If you're servicing a fuel system or fabricating a fuel line run, this kit delivers a selection of durable nitrile (NBR) hoses sized to match common fittings and components. Each hose is 39.37 inches (3.28 ft) long and the set includes 3/16", 1/4", 5/16", 3/8" and 1/2" internal diameters, along with 20 metal clamps so you can secure connections without buying extras. The NBR compound is chosen for heat resistance and fuel compatibility, making the kit suitable for engine-bay routing and aftermarket installations.

Which hose sizes are included and what lengths will I get?

The kit contains five hoses with different inner diameters to fit a wide variety of fuel fittings and carburetor or injector lines. Each hose piece measures 39.37 inches, giving you plenty of length for routing and trimming to size.

• Included IDs: 3/16", 1/4", 5/16", 3/8", 1/2"
• Length per hose: 39.37 inches (3.28 ft)
• Four clamps provided for each size to secure all connections
• Black NBR color for cohesive engine-bay appearance

How does the NBR material perform under engine conditions?

Nitrile butadiene rubber (NBR) is formulated to withstand heat and contact with hydrocarbons, which helps keep the line flexible yet resistant to swelling or hardening from fuel exposure. The hoses are rated for a broad temperature range and pressures typical of automotive fuel systems.

• Temperature range: -40°C to +130°C (-40°F to +266°F)
• Working pressure: 400 psi; maximum pressure: 800 psi
• Designed for fuel delivery lines, routing, and repair where chemical resistance matters
• Black finish resists visible dirt and integrates with engine components

What comes in the package and how do I install the hoses?

The package bundles five hoses and twenty clamps, so you have the right diameter and fasteners for multiple connection points. Installation is straightforward: cut to length, slide on clamps, seat the hose on the fitting, and tighten clamps to form a secure seal.

• Contents: five NBR fuel hoses (each 39.37"), 20 metal clamps
• Trim hose to fit and use provided clamps to prevent leaks
• Compatible with standard barbed fittings, fuel pumps, tanks, and quick connectors
• Inspect and replace clamps or hose ends if signs of wear are present

Will this kit work with my vehicle's fuel system components?

The variety of inner diameters covers most common lines used in automotive and light-truck fuel systems, making the kit useful for repairs and custom plumbing. Confirm the required ID for fuel rails, pumps, or carburetor fittings before cutting to ensure a secure fit.

• Suitable for many gasoline and petroleum-based fuel applications
• Not intended for pressurized diesel common-rail injectors without verification
• Good for fuel pump feed/return lines, carburetor lines, and inline components
• Always match hose ID to the mating barb or fitting for a leak-free connection

Who is this for: The Stacool 5PCS Fuel Line Hose Kit is aimed at DIY mechanics, automotive technicians, and hobbyists who need flexible, fuel-resistant lines in multiple diameters for repair, modification, or custom routing. If you want a single kit that covers common sizes for cars and light trucks and includes clamps for immediate installation, this set provides a convenient, heat-rated solution.
