So your trusty fuel line has finally given up the ghost and you need to replace it. But with all the options out there, how do you choose the right nylon braided fuel line for your needs? Don’t worry, we’ve got you covered. When it comes to something as critical as your vehicle’s fuel system, you want to make sure you’re using a high-quality hose that will stand the test of time and handle the pressure. As the name suggests, nylon braided fuel line has a nylon exterior that provides extra protection and durability. The nylon braid also makes the hose more resistant to abrasions, punctures and weathering.

What Is Nylon Braided Fuel Line?

Nylon braided fuel line is a durable, flexible hose used to carry fuel in vehicles and small engines. It’s made of an inner nylon or polyurethane tube covered by a protective outer nylon mesh. This tough braided sheath prevents kinks, abrasions, and punctures.

Compared to standard rubber fuel line, nylon braided hose is more resistant to damage from heat, oil, and rough or sharp surfaces under the hood. It’s also less likely to degrade over time. For many DIYers and professionals, nylon braided fuel line is the preferred choice for fuel systems in performance vehicles, boats, generators, and other equipment.

When selecting nylon braided hose, you’ll need to determine the correct diameter (measured in inches) for your specific application. The hose should fit snugly over all connectors and fittings to prevent leaks. It’s best to go with a hose rated for use with the type of fuel in your vehicle, whether gasoline, diesel, ethanol blends or methanol.

Nylon braided fuel line typically comes in pre-cut sections or by-the-foot so you can customize the length. Double check that both ends of the hose have the proper end fittings already installed, whether barbed fittings, a fittings or high-pressure quick disconnects. With the right size, rating, and end fittings, nylon braided fuel line will provide a durable solution for your fuel system needs.

Key Factors to Consider When Choosing Nylon Braided Fuel Lines

When choosing nylon braided fuel lines, there are a few key factors to keep in mind.


First, you’ll need to determine what size fuel line you require based on your engine specifications. Fuel line is measured by its inner diameter, typically from 1/4 inch up to 1 inch. Make sure to get the right size for your fuel pump inlet and outlet, as well as your carburetor or fuel injection system. If the line is too small, it won’t deliver enough fuel and your engine performance will suffer. Too large and it won’t connect properly.


Next, consider the material. Nylon braided fuel line is a popular, durable choice as the nylon braiding prevents the line from kinking or crimping. The inner tubing is usually made of nitrile synthetic rubber or nylon that can withstand exposure to fuel like gasoline, diesel and ethanol. Double check that the specific line you choose is rated for your intended fuel type.

Temperature Rating

You’ll also want to check the maximum operating temperature to ensure the line can withstand high engine temperatures, typically ranging from -40 to over 200 degrees Fahrenheit. Higher performance engines usually require lines with higher ‘max temp’ ratings.


Finally, choose a reputable brand that specializes in automotive plumbing and hoses. Cheaper off-brands may seem like a good deal, but can lead to leaks, bursting and engine damage down the road. When it comes to your vehicle’s fuel system, it’s best not to cut corners.

By considering these key factors, you can choose a nylon braided fuel line that will suit your needs and provide safe, long-lasting performance. Your engine will thank you!
