Working on a performance engine build, a restoration project, or just need a super durable fuel line? This 25-foot roll of 6AN (AN6) stainless steel braided hose is professional-grade stuff. The inner tube is made from synthetic CPE material that can handle racing fuel, pump gas, ethanol blends, diesel, oil, and coolant. It's reinforced with a 304 stainless steel mesh braid for strength, then covered with a tough nylon outer sleeve. The inner diameter is 0.34\ (roughly 3/8\), and the outer diameter is about 0.55\. It's rated for crazy pressures – working pressure of 1015 PSI and a burst pressure over 6000 PSI! It can handle temperatures from -40°F to +248°F. You'll need to get the proper AN fittings separately to complete your lines. This hose gives any engine bay a clean, professional look and is miles ahead of standard rubber hose in terms of durability and safety. **Important Note:** This hose is not CARB compliant for street use in California or New York – mainly for off-road or competition use.
