3/8″ × 25′ Nylon Fuel Repair Tubing Coil

When a cracked fuel line threatens your ride, reach for the 4LifetimeLines® 3/8″ × 25′ Nylon Fuel Repair Tubing Coil. This high-strength, petroleum-resistant nylon tubing stands up to E10–E85 blends, gasoline, diesel, and most fuel additives without swelling or softening. Its smooth interior bore delivers unrestricted flow, while crush-resistant walls resist clamp pressure and repeated flexing—even around tight engine-bay curves.

Key Benefits

Chemical & Ethanol Compatibility: Engineered to resist degradation from ethanol-enriched fuels and additives.

Crush-Resistant Durability: Reinforced nylon construction prevents collapse under clamp force, maintaining reliable flow.

Kink-Free Flexibility: Smooth, low-friction bore and supple walls let you bend tubing without restricting fuel delivery.

Wide Temperature Range: Performs flawlessly from –40 °F winter starts to 212 °F under-hood heat.

DIY-Ready Coil: A full 25′ length covers both supply and return lines—simply cut to length and install.

Installation & Usage

Measure the run you need, trim the tubing squarely with sharp snips, and slide on compatible barbed or push-lock fittings. Secure each connection with stainless-steel or OEM-style clamps, route away from hot exhaust and sharp edges, then start the engine and inspect every joint under pressure to confirm a leak-free repair.

Ready to stop that fuel leak? Add the 3/8″ × 25′ Nylon Fuel Repair Tubing Coil to your cart now and drive with confidence.

Nylon Fuel Line
I recently purchased this nylon fuel line for my project, and it exceeded my expectations. The material is strong yet flexible, making installation a breeze even in tight spaces. It handles fuel and pressure exceptionally well, with no signs of leaks or wear after weeks of use. I also appreciated the precise sizing, which fit perfectly without the need for additional adjustments. Overall, this fuel line is durable, reliable, and an excellent value for the price. Highly recommended for anyone looking for a high-quality fuel line! I will continue to purchase from 4life Time lines for any of my line need!
