Crush-Resistant Construction: Reinforced nylon walls prevent collapse under clamp pressure and repeated flexing.
Kink-Free Flexibility: Smooth, low-friction interior lets hose bend around tight engine-bay turns without flow restrictions.
Wide Temperature Range: Operates from –40 °F to 212 °F, ensuring reliability in winter starts and hot-engine environments.
DIY-Friendly Coil: 25′ length gives you enough hose for both supply and return runs on most vehicles—cut to any length you need.
How to Use
Measure & Cut: Determine the required length, then trim the nylon hose squarely with sharp snips.
Install Fittings: Slide on compatible barbed or push-lock fittings, securing with stainless-steel or OEM-style hose clamps.
Route Carefully: Avoid heat sources and sharp edges; use loom or abrasion sleeves if needed.
Test for Leaks: After assembly, start the engine and inspect every connection under pressure.

This fuel line is measured by outside diameter and works with the push-connect type fittings with barbed ends, or even with compression type fittings similar to what is used with copper tubing except for the ones for nylon tubing need to be used with an insert, or the compression fitting itself needs to have the insert built into the fitting. I use Silicone grease from a tube to lubricate the push-connect barbed ends, you can use a heat gun also, but the silicone lube is all I have needed. To hold the nylon fuel line, I sometimes use the appropriately sized dies from my flaring kit clamped in a vise or in the jaws of large vise-grip pliers. Keep this Nylon fuel line away from excessive heat and keep it from rubbing/chaffing on sharp objects and it will last for 15 or more years.
I bought this to the corroded fuel line on GMC Jimmy. This stuff is easy to work with if you have the tool kit for nylon line fittings. Was able to make a new line from the tank to the fuel filter with no issues and the trucks been running great since it was done. Definitely easier than the alternatives.
