5/16″ × 25′ Nylon Fuel Repair Tubing Coil

Don’t let a cracked fuel line strand you—reach for the 4LifetimeLines® 5/16″ × 25′ Nylon Fuel Repair Tubing Coil. This high-strength, petroleum-resistant nylon tubing is formulated to resist swelling, cracking, or degradation when exposed to gasoline, diesel, and ethanol blends up to E85. The smooth bore delivers unhindered fuel flow, while the crush-resistant walls maintain integrity under clamp pressure and repeated flexing around tight bends.

Key Benefits

Ethanol & Additive Safe: Compatible with E10–E85, diesel, and common fuel additives without softening or swelling.

Crush-Resistant Design: Reinforced nylon walls prevent collapse when clamped, ensuring consistent flow.

Kink-Free Flexibility: Smooth interior and pliable material let you route tubing through tight areas without flow restriction.

Temperature-Tough: Performs flawlessly from –40 °F cold starts to 212 °F engine-bay heat.

DIY-Friendly Coil: A full 25′ length covers both supply and return runs—just cut to the exact length you need.

Installation & Use

Measure and trim the tubing squarely with sharp snips, then install compatible barbed or push-lock fittings. Secure connections with stainless-steel or OEM-style clamps, route away from heat and sharp edges, and pressure-test the system to confirm a leak-free repair.


Ready to stop that fuel leak? Add the 5/16″ × 25′ Nylon Fuel Repair Tubing Coil to your cart now and drive worry-free.
