Upgrade your fuel plumbing with the EVIL ENERGY 8AN flare coupler

Designed to connect 8AN lines with a secure straight fit, this EVIL ENERGY pair delivers a sturdy, lightweight solution for fuel system work. Crafted from aluminum alloy 6061-T6 and finished in black, the two couplers offer durable performance without adding unnecessary bulk.

Key features at a glance:

  • Thread size: 3/4-16 UNF for standard 8AN connections
  • 37-degree flare seal delivers reliable seating and minimizes leaks
  • Maximum working pressure: 1,500 PSI for demanding applications
  • Operating range: -40°F to 250°F, suitable for various climates
  • Material: aluminum alloy 6061-T6 for a balance of strength and light weight
  • Configuration: male to male flare coupler with straight through flow

Typical uses include extending fuel hoses, connecting lines to fuel pumps, and integrating with cooler or return lines in a compact, two-piece setup. The aluminum body resists corrosion and maintains a clean, professional appearance under heat and road grime.

What you can expect in real-life setups: quick, tool-friendly installation, snug seal on a standard 8AN hose, and a compact footprint that fits tighter engine bays. While this two-pack does not guarantee universal compatibility, it provides a reliable upgrade option for many OE or aftermarket systems that rely on 3/4-16 UNF flare fittings.

Choosing EVIL ENERGY means opting for consistent performance and a brand with a focus on practical, shop-ready fittings. Use these couplers as part of a careful, well-planned fuel plumbing upgrade and monitor for any leaks during initial testing.

  • Solid aluminum construction keeps weight down without sacrificing strength
  • Secure 37-degree flare seal helps maintain steady pressure
  • Two-pack gives you a ready-to-use replacement or spares
  • Suitable for a range of vehicles and kits that use 8AN hose assemblies
