BRIFITOR 6AN (3/8") 20ft Fuel Line Kit — Nylon-Braided CPE Hose with 23 Swivel Fittings & Clamps

BRIFITOR's 3/8" (6AN) 20-foot fuel line kit is a complete braided hose system with swivel fittings and adapters designed to deliver fuel, oil, and transmission fluids reliably in performance and custom installations.

This kit bundles a long run of durable 6AN hose with a broad assortment of swivel hose-end fittings, couplers and mounting clamps so you can route fuel or oil lines for cars, race builds, or custom projects without sourcing multiple components. The hose combines a chemical-resistant CPE inner lining with a protective nylon-woven outer sheath, and the kit’s fittings cover common connection needs for supply, return, cooler, and adapter points.

How does this kit handle heat, pressure, and chemical exposure?

The hose is engineered to operate across wide temperature extremes and resist typical automotive fluids. Its CPE inner lining resists many oils and fuels while the nylon braid helps protect against abrasion and UV. Pressure ratings give a working range for most fuel and oil system uses, and burst strength provides a safety margin for high-demand situations.

• Working temperature: -100°F to 500°F (-73°C to 260°C)
• Maximum working pressure: 500 psi; burst pressure: 2000 psi
• Compatible with diesel, engine oil, transmission fluid, race gas, hydraulic oil, and vacuum (not recommended for E85)
• Nylon-woven outer sheath for abrasion and corrosion resistance

What fittings and parts are included, and how do they simplify installation?

The kit arrives with 23 pieces selected to cover most common hose routing and connection scenarios. Swivel hose-end fittings allow angled connections and easier assembly, while included couplers and adapters let you join, reduce, or convert fittings without additional purchases. A few clamp pieces help secure hose runs to chassis or brackets during installation.

• 20 ft of 6AN (3/8" ID, 0.33" actual ID) braided hose
• 10 swivel 6AN hose-end fittings and multiple coupler/adapters (flare unions, reducers, NPT adapters)
• 4 hose separator clamps for neat routing and secure mounting
• 1 male flare plug and assorted adapters for common conversions

Will this kit fit my car or project application?

The 6AN size is a common performance plumbing standard used for fuel, return, and oil cooler lines. It suits many street, track, and hobbyist builds but you should verify nozzle sizes, thread types, and compatibility with fluids in your system. Professional or experienced installation is recommended to ensure correct sealing and routing.

• Ideal for fuel supply/return lines, oil or transmission cooler fittings, and custom plumbing
• Adapters include AN-to-NPT and flare couplers to bridge common thread standards
• Not suitable for ethanol blends like E85—check fluid compatibility before use
• Professional installation advised; AN wrenches recommended for assembly

How should I maintain and inspect the hose assembly over time?

Routine visual checks and proper routing are the basics: look for chafe, hardening, or leaks and ensure fittings remain tight. Replace hose if the inner liner shows degradation or if abrasion compromises the outer braid. Using proper clamps and avoiding sharp bends will prolong service life.

• Inspect fittings and hose ends for leaks after first run and periodically thereafter
• Avoid tight 90° bends; maintain smooth routing and secure clamps
• Replace if outer sheath frays, inner liner hardens, or connections leak

Who this kit is for: This BRIFITOR 6AN braided fuel line kit is tailored for automotive enthusiasts, fabricators, and professional mechanics building or upgrading fuel and oil lines on street cars, race vehicles, or custom projects. If you need a long run of quality 6AN hose plus a broad set of swivel fittings and adapters to assemble supply, return, or cooler lines quickly, this all-in-one package reduces the need to source parts individually. If you’re working with ethanol blends (E85) or require specialized certifications, verify compatibility or consult a pro before use.
