Key Features of EVIL ENERGY Fuel Cell

  • Precision Fit for Multiple Vehicles – Available in a range of sizes (including 5, 10, 15, and 20 gallon fuel cells) to ensure the perfect fit for various automotive setups. Installation is quick and straightforward. (See specification sheet for detailed dimensions.)
  • Flexible Mounting Options – Secure installation with mounting tabs sized at 3.46-inch diameter for cubic models and 2-inch for rectangular models, providing stability under demanding driving conditions.
  • Optimized Fuel Flow with AN Fittings – Features 10AN inlet/outlet fittings for most models, and 8AN fittings on the 1-gallon, 15-gallon, and 19-gallon rectangular fuel cells, delivering maximum fuel flow and system compatibility.
  • Fuel Type Compatibility – This fuel cell gas tank is compatible with gasoline, diesel, biodiesel, various oils, grease, water, air, racing gas, and vacuum applications. When using E85 gasoline, methanol, or ethanol, it must be paired with PTFE fuel lines. These fuels are not suitable when used with CPE fuel lines, as they can cause material degradation, swelling, or leakage over time. Following these guidelines helps ensure the longevity and reliability of your fuel delivery system.
  • Premium Aerospace-Grade Construction – Built from 1060-H24 aluminum for a lightweight yet durable structure, paired with a heavy-duty plastic cover for long-lasting reliability.
  • Enhanced Safety with Anti-Slosh Foam – Equipped with built-in anti-slosh foam (on applicable cubic models) to improve fuel pickup and reduce the risk of flashback explosions. Foam should be inspected regularly and replaced if degraded. (Note: Rectangular models do not include anti-slosh foam.)

Note: The built-in anti-slosh foam inside the fuel cell gas tank helps improve fuel delivery, stabilize fuel flow, and reduce the risk of flashback explosions. For optimal performance and safety, inspect the foam regularly and replace it if signs of wear or deterioration appear.

EVIL ENERGY Fuel Pressure Regulator

This adjustable fuel pressure regulator is engineered for most EFI fuel cell systems and supports both gasoline and E85 fuels. Designed for performance and reliability, it ensures precise fuel delivery across a wide range of applications. For a secure, leak-free installation, always apply thread sealant tape to the NPT pressure gauge port.

Key Features

  • Wide Adjustable Fuel Pressure Range – Fine-tune fuel delivery with adjustment settings of 20–120 PSI, 30–70 PSI, or 30–140 PSI, enabling optimal performance in street, track, turbocharged, or high-horsepower setups.
  • Universal Fitment – Equipped with 6AN and 10AN fittings, this fuel cell pressure regulator integrates seamlessly into most aftermarket and custom EFI fuel systems, including LS engine swaps, boosted applications, and race builds.
  • High-Strength Aluminum Construction – Built from durable, corrosion-resistant aluminum to withstand extreme temperatures, vibration, and demanding driving environments.
  • Bypass Return Functionality – Maintains consistent fuel pressure by returning excess fuel to the tank, preventing pressure spikes, improving stability, and protecting injectors and pumps.
  • Gasoline & E85 Compatible – Ready for both gasoline and ethanol-based fuels, making it ideal for modern EFI performance builds requiring versatility and reliability.

EVIL ENERGY Fuel Filter 10/30/40/100 Micron

Engineered for precision fuel filtration, this fuel cell filter ensures clean, consistent fuel delivery by capturing fine debris and contaminants before they reach your injectors or carburetor. Ideal for EFI fuel cell systems and performance builds, it offers both protection and longevity.

Key Features

  • Multiple Micron Ratings – Choose from 10, 30, 40, or 100 micron elements to match your filtration needs, from ultra-fine EFI protection to high-flow racing setups.
  • Stainless Steel Filter Element – Effectively traps contaminants while maintaining optimal fuel flow. The reusable element is easy to remove, clean, and reinstall, reducing long-term maintenance costs.
  • Fuel Type Compatibility – Works with gasoline, diesel, and ethanol-based fuels including E85, offering flexibility for modern and custom performance applications.
  • Durable, Corrosion-Resistant Housing – Constructed from anodized aluminum to withstand high-pressure environments and resist corrosion, ensuring reliable performance in demanding conditions.
  • EFI & Carburetor Friendly – Designed for use in both EFI and carbureted fuel cell systems, making it a versatile upgrade for street, track, and off-road builds.

FAQs

1. What exactly does the kit include?

The kit is a modular system that includes:

  • A fuel cell gas tank (available in ½‑, 5, 10, 15, or 20‑gallon capacities)
  • An adjustable fuel pressure regulator (available in 30–70 PSI, 20–75 & 75–120 PSI, or 30–80 & 80–140 PSI ranges)
  • A fuel filter (choice of 10, 30, 40, or 100‑micron element)
    Each component can be opted out if not needed (e.g., without cell, filter, or regulator) — allowing tailored configurations. 

2. Can I mix and match components like a fuel cell, filter, and regulator?

Yes. The product page allows full flexibility. You can choose a combination with or without:

  • The fuel cell gas tank
  • The fuel pressure regulator
  • The fuel filter
    This makes it versatile for custom builds or upgrades. 

3. What fuel types is this kit compatible with?

  • The fuel cell supports gasoline and E85, particularly when using PTFE (Teflon-lined) fuel lines for fuel compatibility safety. 
  • The fuel pressure regulator and fuel filter are also compatible with gasoline, diesel, and ethanol-based fuels. Note: Some regulators listed elsewhere may exclude diesel — always check the variant specifics. 

4. What is the purpose of the adjustable fuel pressure regulator?

The adjustable fuel pressure regulator:

  • Maintains consistent fuel pressure by returning excess fuel to the tank
  • Offers flexibility with three pressure ranges: 30–70 PSI, 20–75 & 75–120 PSI, and 30–80 & 80–140 PSI
  • Ideal for fine-tuning fuel delivery across various performance applications — street, track, or race builds. 

5. What maintenance should I perform?

  • Fuel Filter: Replace or clean based on the selected micron rating. Reusable stainless steel elements are easy to service and reduce long-term cost. 
  • Anti‑Slosh Foam (in fuel cell): Inspect regularly and replace if it appears degraded to ensure stable fuel delivery and prevent flashbacks.

6. How do I install the fuel pressure regulator safely?

When installing:

  • Use thread sealant tape (Teflon tape) on the NPT port for the pressure gauge to prevent leaks.
  • The kit is designed for EFI returnless systems, so ensure proper venting and return flow capability.
  • Always follow general safety practices: relieve system pressure before removal, wear eye protection, and perform a leak check after installation. 

7. Is this kit suitable for both fuel cell system builds and standalone use?

Absolutely.

  • It works as a complete fuel cell kit (tank + filter + regulator) for integrated EFI returnless systems.
  • You can also purchase individual components (e.g., just the pressure regulator or filter) for standalone applications or retrofits.
