EVIL ENERGY 6AN Fuel Line Kit (6AN Nylon Braided Hose, 20 ft) with Swivel Ends & AN Fittings

If you’re building or upgrading an engine bay where lines get moved around, a braided AN-style fuel line kit is often the cleanest way to tidy everything up. This EVIL ENERGY 6AN Fuel Line Kit is designed around a 6AN hose setup with braided protection and multiple hose end angles, so you can route a supply or return line without fighting bends.

That said, it’s not a universal “every car, every scenario” solution. It’s a hose-and-fitting kit with specific hose size (ID and OD) and an indicated pressure/temperature envelope, so you’ll still want to sanity-check fitment and routing before you commit.

Key takeaways on what it is and what it’s for

This kit is built for 6AN plumbing using a nylon-braided fuel line hose. On paper, it’s a flexible option for more than just fuel—commonly used for things like fuel supply/return lines, transmission oil cooler lines, vacuum lines, turbo cooler lines, and oil feed lines. It’s also described as compatible with a range of fluids such as transmission fluid, oil, race gas, hydraulic fluid, diesel, and fuel.

Where it makes sense is in projects that need routing flexibility and a more finished look under the hood. The braided exterior helps protect the hose, while the inner material and steel reinforcement are there to keep the line structure more stable than plain rubber hose.

What you’ll notice in everyday routing and installation

The kit includes hose ends in several bend-friendly styles: straight, 45-degree, 90-degree, and 180-degree. That matters because most engine bays don’t give you perfect straight-line runs. Being able to choose the angle of the swivel hose ends can save time and reduce the “creative” routing that can cause kinks.

You also get hose separator clamps (for managing line spacing and keeping things from rubbing). Again, not glamorous, but in real installations it’s the difference between a line that stays neat and one that slowly works loose from vibration or heat cycling.

One practical micro-example: if you’re running a return line from a mount location to a nearby reservoir or fitting, you can pick a 90-degree end to clear a bracket, then use a 45-degree where you need to transition toward the fitting. It’s a small thing, but it’s exactly the kind of choice that helps keep hoses from crossing hot components.

The specs that matter (and the limits to respect)

This kit lists a maximum working pressure of 500 psi, with a stated bursting pressure of 2000 psi. It also lists a temperature range from -22°F to 248°F.

Those numbers are useful for decision-making, but it’s still worth noting the limitation: the safest approach is to ensure your application’s pressure and temperature conditions fall comfortably within what the kit is rated for. If you’re pushing conditions beyond typical use (or you’re unsure), you may want to pause and confirm compatibility rather than assume it’s fine.

Also pay attention to the hose size. The hose ID is 0.34 inch and the hose OD is 0.54 inch. That’s the kind of detail that can make or break fit if you’re matching to existing AN components or routing clips.

Materials and build: what’s inside the braided line

The hose is described as having a CPE rubber inner, with a layer of 304 steel wire and a nylon outer braid. That combination is aimed at durability and protection while still keeping the line manageable for routing.

The fittings are listed as aluminum alloy. Over time, aluminum fittings can be great for light, tidy installs—but you still want to treat threads and sealing surfaces carefully during assembly and avoid cross-threading.

If you’re hoping for a “drop-in and forget it” result, it won’t feel that simple: installation quality depends on how well you route the line, manage strain, and assemble the hose ends properly.

Where it shines vs. when you should skip it

This EVIL ENERGY kit is a solid fit if your priority is a braided 6AN fuel line setup with multiple end angles and a 20 ft length for a project that needs some flexibility in routing. If you’re doing a DIY or shop-style build where you want a more polished engine bay look—and you can work within 6AN hose sizing—this is the kind of kit you’d reach for.

It may not be the best choice if: - You need a different AN size than 6AN (the kit is centered on 6AN). - Your application requires a hose size or routing approach that doesn’t match the listed hose ID/OD. - You’re unsure about pressure/temperature conditions and want something you can assume without checking ratings.

In other words, it’s more “project-focused kit” than “generic replacement hose.” If your goal is to match an existing setup precisely, measure twice and verify the connection style and hose dimensions first.

What’s included in the package

The kit includes 10 pcs of 6AN swivel hose ends (4 straight, 2 of each 45-degree and 90-degree, and 2 of 180-degree), 6 pcs of 6AN hose separator clamps, plus 2 pcs of 6AN to 6AN fittings.

It also includes 20 ft of 6AN braided fuel line. That means you’re not just buying hose—you’re getting the key parts commonly needed to assemble a multi-route build.

Getting the most from it (buyer checklist)

Before purchasing, here’s what’s worth confirming so you don’t run into avoidable headaches: - Your planned lines are actually 6AN compatible. - Your routing needs justify having multiple end angles (especially straight vs. 45/90/180). - Your application’s pressure and temperature conditions are within the kit’s stated working range. - Your existing clamps, clips, or routing points won’t fight the hose OD (0.54 inch).

If you prioritize a tidy installation and you’re comfortable doing a proper line assembly, this kit gives you the parts to make that easier.

Final verdict

Should you buy it? This EVIL ENERGY 6AN Fuel Line Kit is worth considering if you want a braided, reinforced 6AN hose setup with multiple swivel end angles and a 20 ft length for fuel, return, or other listed fluid-routing use cases. The materials and listed pressure/temperature range are there to support serious routing, not just cosmetic upgrades.

You may want to skip it if you’re not sure your application stays within the stated working pressure/temperature limits, or if you’re matching an existing system where the hose ID/OD or 6AN connection style doesn’t line up. On this one, “measure the routing and confirm the match” is the difference between a smooth install and an annoying return.
