Upgrade your vehicle with the EVIL ENERGY EFI Fuel System Kit!
This comprehensive kit includes a 10 Micron Filter with Bracket, a powerful 300LPH high flow fuel pump, and durable fuel lines made from PTFE. It also comes with a 10-micron fuel filter and all necessary fittings for easy installation.

Build a clean, reliable EFI fuel setup while retaining your existing fuel pump. This kit combines an adjustable fuel pressure regulator, a washable 10-micron stainless steel inline fuel filter with mounting bracket, and matched AN fittings for vehicles with OEM-style returnless fuel rails. Choose a configuration with or without the 6AN-to-3/8-inch quick-release fitting to match your connection.

Fuel pump and fuel lines are not included. Verify the required pressure range, port sizes, fuel compatibility, and rail configuration before ordering.

The EVIL ENERGY 10 gallon fuel tank kit is a complete fuel-delivery solution for LS swaps and EFI conversions that require more pressure and flow than an original carbureted fuel system can provide.

Instead of purchasing a bare 10 gallon fuel cell and sourcing the pump, filters, regulator, AN fittings and hoses separately, this all-in-one kit reduces compatibility issues, missing parts and installation rework.

Choose between two hose kit configurations:

• CPE Fuel Hose Kit: Includes 40 ft of fuel line and a standard fitting package. Best suited for compact vehicles, drift cars and straightforward EFI swaps.
• CPE & Vacuum Hose Kit: Includes 60 ft of line, vacuum hose, 180-degree fittings and a Y-block. Designed for long-wheelbase vehicles, turbocharged builds and high-flow dual-fuel-rail systems.

Each 10 gallon fuel cell kit combines an external fuel pump, dual-stage fuel filtration, an adjustable fuel pressure regulator, AN fittings and internal anti-slosh foam to support more consistent fuel delivery during acceleration and hard cornering.

Core Performance & Compatibility

• 650 CFM 4-barrel design: Performance upgrade for stock to mildly modified V-8 engines (street-focused power & drivability)
• Mechanical secondary throttle: Immediate, lag-free acceleration for street driving and cruising
• Compatible with GM, Ford, Chrysler AT shift linkages (specific setups may require additional parts)

Convenience & Tuning

• Factory preset electric choke: Automatic temperature adjustment for easy cold starts (no manual choke hassle)
• Pre-calibrated: #70 main jets / #74 secondary jets / 0.031-inch pump nozzle—ready for street use out of the box; fine-tuning optional
• Complete kit: Includes all fuel system accessories (hose, filter, pump, regulator, fittings) to avoid separate purchases

Installation & Build

• 100% new components: 3.25-inch height, square bore flange—fits most street engine bays
• Durable build: Shiny aluminum carburetor + 20FT AN6 push-lock hose + 110LPH 12V fuel pump—built for long-term street reliability
• Dual-precision filtration: 100/40 micron filters protect the carburetor and engine from debris; 5-12 PSI regulator maintains stable fuel pressure

The EVIL ENERGY 15 Gallon Fuel Cell fits most custom builds with at least 19.88 × 17.91 × 10.03 inches of available space for secure mounting and plumbing. Its internal safety foam controls fuel slosh, supports steadier fuel delivery, and helps reduce fuel movement during impacts. Ideal for racing, drifting, and long-distance builds.
