About this item
-
Tri-Layer Durable Hose Construction: Outer nylon layer resists abrasion (ideal for engine bay friction), inner CPE core is oil/fuel-resistant (compatible with transmission fluid, race gas), and 304 stainless steel wire reinforcement prevents expansion under pressure—ensuring long-term reliability.
-
5 Size Options for All Needs: 4AN (small vacuum lines)、6AN (standard fuel/transmission lines)、8AN (mid-flow turbo coolers)、10AN (high-flow fuel supply)、12AN (heavy-duty oil feed lines); each kit includes a 10FT hose, covering most automotive fluid system demands.
-
Extreme Environment Adaptability: -22℉ to 248℉ temperature range handles cold winters and hot engine bays; pressure ratings (up to 750psi working, 2250psi burst) meet safety standards for street, off-road, and racing use.
-
Versatile Applications: Perfect for transmission oil cooler lines, fuel return/supply lines, coolant hoses, vacuum lines, turbo cooler lines, and fuel gauge lines—one kit fits multiple system upgrades.
-
Complete Ready-to-Install Kit: Comes with 6 swivel fittings (straight/45°/90°) for flexible routing and 2 hose separator clamps (reduces vibration noise); no extra parts needed for most installations.
-
Precise Fit Guarantee: Clear ID/OD dimensions and AN sizing ensure compatibility with aftermarket or OEM components; note: measure your vehicle’s existing lines/fittings before purchase to avoid mismatch.
Product Description
The EVIL ENERGY Fuel Line Kit is a professional-grade solution for upgrading or repairing vehicle fluid systems, designed to balance durability, versatility, and ease of installation. Its tri-layer hose (nylon+CPE+304 steel wire) solves common pain points of generic lines—abrasion damage, oil leakage, and pressure expansion—making it suitable for both daily drivers and performance builds (e.g., LS V8 swaps, turbocharged cars).
Each size is tailored to specific needs: 4AN for compact vacuum lines, 6AN/8AN for standard fuel/transmission use, 10AN/12AN for high-flow scenarios (e.g., racing fuel supply). The swivel fittings rotate 360°, eliminating alignment issues during installation, while hose separator clamps keep lines organized and reduce vibration noise. Compatible with transmission fluid, oil, race gas, and standard fuel, it’s a one-stop kit for most automotive fluid system upgrades.
Why Choose Evil Energy?
At EVIL ENERGY, we focus on solving real-world automotive upgrade challenges—from fitment issues to durability concerns—by engineering components that meet the needs of enthusiasts and professionals alike.
1. Professional Fitment for LS V8 & Performance Builds
-
Generic Kits Fail at Specific Needs: Most fuel line kits lack optimization for LS V8 engines (Cadillac/Chevrolet/GMC/Hummer/Pontiac 2007-2015), leading to mismatched fittings or insufficient flow.
-
EVIL ENERGY Precision: Our kits are calibrated for LS V8 fluid system specs—AN sizes match OEM/aftermarket components, and swivel fittings fit tight engine bay spaces common in LS swaps, ensuring hassle-free installation.
2. Rigorous Quality Control for Longevity
-
Cheap Lines Degrade Quickly: Low-grade hoses crack under temperature changes, and fittings corrode—causing leaks that damage engines or transmissions.
-
EVIL ENERGY Durability: Each hose undergoes pressure testing (up to 2250psi burst) and temperature cycling; aluminum alloy fittings are anodized to resist corrosion, ensuring 3+ years of reliable use.
3. Complete Kits Save Time & Money
-
Fragmented Sourcing Causes Headaches: Buying hoses, fittings, and clamps separately often leads to compatibility issues (e.g., fitting threads don’t match hose size) and repeated trips to the store.
-
EVIL ENERGY Convenience: All components in one box—10FT hose, 6 swivel fittings, 2 clamps—no extra purchases needed. Clear labeling helps beginners identify parts quickly.
4. Customer-Centric Service & Support
-
Fast Shipping: Orders processed within 1-2 business days, with most deliveries arriving in 3-5 days—get your project back on track quickly.
-
Hassle-Free Returns: 90-day free return policy (unused, intact packaging); 90-180 days with 15% restocking fee—no risk if the kit doesn’t fit.
-
1-Year Warranty & Expert Help: Warranty covers manufacturing defects; our team (with 5+ years of automotive experience) answers installation questions via support@ievilenergy.com within 24 hours.

FAQ
Q: How do I choose the right AN size for my vehicle?
A: Match the size to your fluid system’s flow needs: - 4AN: Vacuum lines, small fuel gauge lines
- 6AN: Transmission cooler lines, standard fuel return lines
- 8AN: Turbo cooler lines, mid-flow fuel supply
- 10AN: High-performance fuel supply (e.g., V8 engines)
- 12AN: Heavy-duty oil feed lines (e.g., big turbo setups)
Pro tip: Check your vehicle’s OEM line size or aftermarket component specs (e.g., fuel pump outlet) for compatibility.
Q: Can this fuel line be used with E85 ethanol?
A: The CPE inner core is compatible with E85, but avoid using nylon braided outer layers with E85 for long-term use (ethanol can degrade nylon over time). For E85 setups, we recommend wrapping the hose with heat-resistant tape or choosing our PTFE-lined E85-specific kits.
Q: Do I need special tools to install the swivel fittings?
A: No—standard wrenches work. Tighten fittings to 15-20 ft-lbs (avoid over-tightening, which can damage threads). For better sealing, apply a small amount of thread sealant tape (not included, but compatible) to male threads.
Q: What if the 10FT hose is too long for my installation?
A: You can safely cut the hose with a sharp utility knife or hose cutter. Ensure the cut end is clean (no frayed wires) before attaching fittings—trim 1-2 inches if the end is damaged during cutting.
Q: Is this kit compatible with my 2010 Chevrolet Camaro SS (LS3 V8)?
A: Yes—we recommend the 8AN kit for LS3 fuel supply lines and 6AN for transmission cooler lines. The swivel fittings fit the Camaro’s tight engine bay, and the hose length is sufficient for most stock or mild modified setups.
Q: Does the warranty cover leaks caused by improper installation?
A: No—the 1-year warranty covers manufacturing defects (e.g., faulty fittings, hose cracks). Leaks from over-tightening, incorrect cutting, or mismatched components are not covered. If you’re unsure about installation, contact our support team for guidance first.
