EVIL ENERGY 10AN 90° Push-Lock Fuel Adapter — 10AN (7/8-14 UNF) to 5/8" Barb, 6061-T6 Aluminum, 2-Pack

EVIL ENERGY's 10AN 90° push-lock fitting converts a 10AN 7/8-14 UNF threaded line to a 5/8" barb for rubber fuel hose connections, sold as a two-piece set.

This compact aluminum adapter is built for performance plumbing where a sturdy push-lock connection must transition to a flexible rubber fuel hose. Machined from 6061-T6 aluminum, the 90-degree profile minimizes routing stress and helps tuck plumbing into tight engine bays, while rated pressure and temperature ranges cover most automotive and motorsport applications. The kit contains two fittings and is optimized for use with clamps on rubber fuel lines.

How does this fitting make routing fuel lines easier in tight spaces?

The 90° elbow redirects flow without long, bulky hoses or extra couplers, simplifying clean routing and freeing up room around headers, steering, or suspension components. Its compact form reduces hose abrasion and helps avoid awkward bends that can restrict flow.

• Right-angle design saves space behind manifolds and near turbos
• Short overall length minimizes exposed hose sections
• Smooth internal passage reduces turbulence at the joint

Is this fitting compatible with my hose and plumbing system?

This adapter joins a 10AN male-threaded line (7/8-14 UNF) to a 5/8" barb intended for rubber fuel hoses only. It does not fit hard lines or push-lock plastic tubing unless those lines are adapted to the specified sizes. Always match thread type and hose inner diameter to ensure a leak-free connection.

• Thread: 10AN (7/8-14 UNF) female/male interface compatibility
• Barb: 5/8" designed specifically for rubber fuel hose inner diameter
• Not recommended for PTFE or rigid tubing without additional adaptors

What performance limits and materials should I expect?

Manufactured from 6061-T6 aluminum, the adapter balances light weight with good corrosion resistance for fuel-system use. It's rated to a maximum working pressure of 1,500 PSI and operates across a wide temperature range, making it suitable for many automotive and racing environments when used within those limits.

• Material: 6061-T6 aluminum alloy for strength and reduced weight
• Pressure: rated up to 1,500 PSI under proper hose and clamp installation
• Temperature range: -40°F to 248°F (suitable for typical engine bay temperatures)

How should I install and secure the barb fitting to prevent leaks?

Push the rubber hose onto the 5/8" barb until it seats fully, then install a quality clamp to compress the hose onto the barb for a reliable seal. The fitting threads into a 10AN 7/8-14 UNF port; use appropriate thread tape or sealant where required by your system, and torque to recommended specifications for AN fittings.

• Push hose fully onto the barb and position clamp over the barb ribs
• Use stainless worm-drive or crimp-style clamps for best sealing
• Apply AN thread sealing method if your installation requires it

Who is this for? This two-piece EVIL ENERGY 10AN 90° push-lock to 5/8" barb adapter suits automotive enthusiasts, fabricators, and racers who need compact, durable transitions from AN-threaded plumbing to rubber fuel hose. It’s ideal for custom fuel systems, retrofit projects, or repairs where space is limited and a robust sealed connection is required. If you work with rubber fuel lines and 10AN fittings, this aluminum elbow offers a practical, compact solution — remember to use appropriate clamps and confirm thread/hose sizing before installation.
