EVIL ENERGY 4AN Fuel Line Kit 20ft Braided Hose - Versatile

Our review of the EVIL ENERGY 4AN Fuel Line Kit finds it best suited for enthusiasts and DIY mechanics who need a long, versatile hose run with multiple fittings for fuel, transmission cooler, turbo cooler or vacuum applications. The single biggest reason to buy is the 20 ft of braided 4AN hose combined with a kit of ten swivel ends, which makes routing and adapting lines much easier than piecing parts together. In practice the kit balances value and functionality for one-off projects and custom plumbing in garages and race support setups.

Key Features

• 20 ft Braided Hose: Provides ample length to reach from tanks to coolers or pumps without splices, reducing leak points.
• Multiple Swivel Ends: The 10 included 4AN hose ends with straight and angled fittings speed installation and simplify tight routing.
• Durable Construction: CPE rubber inner with 304 stainless wire and nylon outer braid gives a good balance of flexibility and abrasion resistance.
• Wide Compatibility: Rated for fuel, diesel, transmission fluid, oil and hydraulic fluids, so it can be used across several systems.
• Pressure & Temperature Range: 750 psi working pressure and a -22F to 248F temperature window cover most street and light track uses.
• Aluminum Fittings: Lightweight alloy swivel ends help reduce weight and corrosion concerns compared with lower quality materials.

Who It's For

This kit is ideal for car builders, tuners and hobbyists who need a long run of 4AN hose with a variety of fittings to complete custom fuel or cooler plumbing without multiple separate purchases. The included swivel ends and clamps make it practical for one-off installations in engine bays, transmissions cooler loops, and turbo feed or return lines.

It is less appropriate for users who require certified OEM replacement hoses for factory warranty work or applications outside the specified temperature and pressure range. Also, buyers seeking pre-assembled, length-cut specific lines for a production vehicle may prefer custom-made hose assemblies from a specialist.

Pros & Cons

Pros

• Good value: long 20 ft length plus ten fittings covers multiple runs and reduces extra purchases.
• Versatile: compatible with fuel, oil, transmission fluid and hydraulic fluid for broader workshop use.
• Practical fittings: included straight and angled swivel ends simplify routing and reduce stress on connections.
• Attractive finish: nylon braid and alloy fittings give a professional look under the hood.

Cons

• Mixed durability reports: some users have reported failures after heavy use, so for extreme racing duty a purpose-built race hose may be preferred.
• Not a drop-in OEM replacement: requires fitting and trimming, which may not suit novice installers.
