Stainless Steel Fuel Line 5/16" (7.9mm) 25ft (7.6m) Length Roll

Upgrade to Aeroflow Performance Stainless Steel Fuel Line 5/16" (7.9mm) 25ft Roll for a durable, high-performance routing solution that stands up to demanding applications. Crafted from 304 stainless steel, this seamless hard line delivers aircraft-quality reliability for fuel, brake, or oil lines where flexible hose isn’t practical.

Why choose this stainless hard line

• Aircraft-quality 304 stainless steel, seamless thin-wall tube for consistent performance
• Rated up to 6000 psi, ideal for high-demand fuel systems and race-inspired builds
• 25-foot roll in a 5/16" outside diameter (7.95 mm) for clean, continuous runs along chassis or frame rails
• Designed for use with tube line adapter fittings or when using a flaring tool with tube nut/tube sleeve combinations
• ASTM-A269 standards-compliant stainless steel tube for dependable, long-lasting service

Important installation considerations

• Stainless steel is more challenging to bend and flare than typical steel lines; a professional-grade flaring tool is recommended
• Sealing can be difficult when replacing an existing brake or fuel line; wear patterns on the flare seat may prevent a proper seal
• When replacing lines, thoroughly inspect related components (fittings, junctions, calipers, and blocks) to ensure a proper seal
