The kit's 10 ft length and AN4 (ID 3\/16'') sizing make it a practical choice for routed fuel systems, though buyers should measure carefully and plan for professional installation because the hose is relatively stiff.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eID and length:\u003c\/strong\u003e The 3\/16' (0.19 in) inner diameter and 10 ft length provide enough hose to route fuel for many single-engine applications without buying extra material.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature range:\u003c\/strong\u003e Rated from -76F to 446F (-60C to 230C), the hose resists heat in engine bays and under-hood locations where ordinary rubber lines would soften.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh pressure capability:\u003c\/strong\u003e A 1500 psi maximum working pressure and 4500 psi burst pressure deliver confidence for high-pressure fuel systems and return lines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial construction:\u003c\/strong\u003e PTFE core with nylon braid offers chemical compatibility with automotive fuels including ethanol blends and increased abrasion resistance compared with bare PTFE.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Suitable for all automotive fuels, lubricants, and coolants, making it versatile for fuel feed, return, and some fluid-transfer uses.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation caution:\u003c\/strong\u003e The hose is relatively hard and resists tight bending, so planning and proper fittings are important for a leak-free installation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis kit is for mechanics, fabricators, and enthusiasts installing or upgrading AN4 fuel lines where high temperature and pressure resistance matter, such as turbocharged or race-inspired builds and conversions using E85 or other aggressive fuels.
