Podavelle 3/8" OD Aluminum Hard Fuel Line Hardline Tube

Podavelle 3/8" OD aluminum hard fuel line is a 25-foot coil of 3003-grade tubing designed for easy cutting, bending, flaring and reliable service at up to 650 psi.

This coiled hardline tube from Podavelle is engineered for mechanics, fabricators and hobbyists who need lightweight, corrosion-resistant tubing for fuel, oil, water or air systems. The tubing measures 3/8 inch (9.52 mm) outside diameter with a 0.035 inch (0.89 mm) wall thickness, providing a balance of flexibility and strength for custom runs and repairs. Extruded from 3003 aluminum alloy, the line offers good formability and surface finish for polishing or fitting when used with standard tube nuts, sleeves and 37° flared AN fittings.

What are the core dimensions and material characteristics?

The coil is specified as 3/8" (9.52 mm) outside diameter with a 0.035" (0.89 mm) wall thickness and a total length of 25 feet (7.62 meters). It’s extruded from 3003-grade aluminum, which is chosen for its workability and natural corrosion resistance compared with bare steel.

• Outside diameter: 3/8 inch (9.52 mm)
• Wall thickness: 0.035 inch (0.89 mm)
• Coil length: 25 ft (7.62 m)
• Material: 3003 aluminum alloy—good formability and finish

How does this tubing perform under pressure and which fluids is it compatible with?

The Podavelle hardline is rated to a maximum working pressure of 650 psi, suitable for many low- to mid-pressure fuel and fluid system applications. It is compatible with fuels and fluids such as gasoline, diesel, ethanol blends (including E85), oil, water and air when installed correctly with compatible fittings.

• Maximum working pressure: 650 psi
• Compatible fluids: fuel, oil, water, gasoline, diesel, ethanol/E85, compressed air
• Recommended fittings: tube nut couplers, sleeves, 37° flared AN fittings

Can I shape, flare or join this tubing for custom plumbing and fuel lines?

Yes — 3003 aluminum is readily cut, bent and flared, making this coil well suited to custom routing and fabrication tasks. Use standard tubing cutters, bending tools, and a 37° flaring tool for AN-style fittings; always follow proper flaring and joining procedures to ensure leak-free connections.

• Easy to cut with a tube cutter or fine-tooth saw
• Formable for manual or machine bends; avoid kinking
• Compatible with 37° AN flares, tube nuts and sleeves for assembly

How should the tubing be stored and prepared before installation?

Keep the coil clean and dry while stored to protect the finished surface and minimize contamination. Before installation, deburr the cut ends, inspect flares or fittings for proper seating, and secure the tubing with clamps or brackets to prevent vibration wear.

• Store coiled in a dry, covered area to prevent dirt or moisture buildup
• Deburr and clean cut ends for safe, leak-free fittings
• Use clamps or supports to reduce vibration and abrasion in service

Who is this for: Podavelles 3/8" OD aluminum hardline is intended for automotive builders, custom fabricators, restoration projects, marine fitters and DIY mechanics who need a balance of light weight, corrosion resistance and practicality for fuel, oil, water or air systems. It suits anyone creating custom runs, replacing corroded lines, or adapting systems to ethanol blends and other compatible fluids. Make sure to match fittings and installation practices to your systems pressure and fluid requirements for safe, durable results.
