Tips for taking the cap off:
The EVIL ENERGY 15 Gallon Fuel Cell provides additional fuel capacity for racing, drifting, long-distance driving, and custom builds. This universal aluminum fuel cell measures 19.88 × 17.91 × 10.03 inches (L × W × H) and features 3.64-inch mounting tabs. If your vehicle has sufficient space for the tank and adequate clearance for secure mounting, fuel lines, and ventilation, this fuel cell is worth considering. It features TIG-welded aluminum construction with walls over 2 mm thick, reinforced seams and corners, AN10 outlets, anti-slosh foam, and a built-in 3–90-ohm fuel level sender. AN fittings made from aerospace-grade 6061-T6 aluminum provide secure, durable connections. Before installation, verify mounting strength, fuel compatibility, ventilation, and compliance with local vehicle modification requirements.

Building a custom fuel system usually requires matching the fuel tank, fuel pump, fuel filters, fuel pressure regulator, fuel line, and fittings. This EVIL ENERGY Fuel Cell kit combines the main fuel-delivery components for racing, drifting, long-distance projects, engine swaps, restorations, and other custom builds.
The universal 15 Gallon Fuel Cell is not designed for one specific vehicle. It may be considered when the vehicle has sufficient installation space, secure mounting points, plumbing clearance, ventilation, and service access. Custom mounting, wiring, and fuel-line routing are required.
A typical external electric fuel pump, return-style EFI fuel system follows this flow:
15 Gallon Fuel Cell → 100-Micron Fuel Filter → 12V Inline Fuel Pump → 10-Micron Fuel Filter → Fuel Rail and Injectors → Fuel Pressure Regulator → Return Line → Fuel Cell
The exact position of the Fuel Pressure Regulator may vary with the fuel rail, regulator type, and system design. Follow the instructions supplied by the engine, fuel rail, and regulator manufacturers.
This EVIL ENERGY 15 Gallon Fuel Cell Kit is a universal custom-installation system, not a vehicle-specific direct-fit replacement. Vehicle make and model alone do not determine fitment. Installation may be considered when the vehicle provides sufficient space, structural support, plumbing clearance, ventilation, and electrical access.
Before ordering, verify the following requirements:
The kit includes 3/8-inch aluminum hard line. Properly rated CPE or PTFE fuel lines may be added where flexible connections are required, but flexible hose is not included. CPE and PTFE hose use different construction and may require different hose ends.
Selected AN fittings and adapters are precision-machined from aerospace-grade 6061-T6 aluminum. This material provides a lightweight and corrosion-resistant connection for compatible automotive fuel-system applications.
Correct fitting selection and installation help reduce the risk of fuel seepage and pressure loss. Verify the AN size, thread type, flare surface, tube or hose specification, and required sealing method. AN fittings seal at the flare surface, so thread sealant should not be applied to the AN flare.
The complete EVIL ENERGY 15 Gallon Fuel Cell Kit is compatible with the following fuels:
Fuel compatibility applies to the included fuel cell, internal anti-slosh foam, fuel pump, fuel filters, fuel pressure regulator, seals, aluminum hard line, AN fittings, adapters, and O-rings.
Any separately purchased hose, fitting, or replacement component must also be rated for the selected fuel.

Installation and testing should be performed by someone familiar with automotive fuel plumbing. Stop using the system immediately if leakage, damaged wiring, abnormal pump noise, unstable pressure, or other unsafe conditions are found.

The EVIL ENERGY 15 Gallon Fuel Cell Kit combines an aluminum fuel cell, 300LPH external fuel pump, dual-stage filtration, adjustable 20–120 PSI regulator, 3/8-inch aluminum hard line, and AN fittings for custom return-style EFI fuel systems. The universal fuel cell measures 19.88 × 17.91 × 10.03 inches (L × W × H). Custom mounting, plumbing, ventilation, and wiring are required.
The 15-gallon fuel cell is manufactured from aluminum alloy with walls over 2 mm thick. TIG-welded seams, reinforced corners, and mounting tabs create a rigid enclosure for demanding custom and motorsport applications.
Internal anti-slosh foam helps limit fuel movement inside the tank during:
Controlling fuel movement can support steadier fuel pickup and reduce sudden changes in fuel weight distribution. The foam does not eliminate vapor lock or replace correct fuel-system ventilation. Confirm compatibility between the internal foam and the intended fuel before filling the tank.
The EVIL ENERGY fuel system kit includes two Inline Fuel Filters that filter contaminants at different stages of fuel delivery. The 100-Micron Fuel Filter is installed before the electric fuel pump, while the 10-Micron Fuel Filter is installed after the electric fuel pump.
The 100-Micron Pre-Pump Inline Fuel Filter captures larger particles before fuel enters the 12V Inline Fuel Pump. This helps reduce contamination-related electric fuel pump wear while avoiding the excessive inlet restriction that may be caused by an overly fine pre-pump filter.

The 10-Micron Post-Pump Inline Fuel Filter removes smaller contaminants after fuel exits the 300LPH Inline Fuel Pump. This finer filtration stage helps protect the fuel rail, injectors, and other precision EFI components.

The 12V Inline Fuel Pump moves fuel from the EVIL ENERGY 15 Gallon Fuel Cell toward the engine. Its external design supports flexible placement in custom return-style EFI fuel systems for racing, drifting, classic trucks, engine swaps, restorations, and other performance builds.
The 300LPH Inline Fuel Pump is rated for flow up to 300 liters per hour under specified test conditions. The rating describes pump flow capacity and does not mean the electric fuel pump will deliver 300 LPH under every operating condition.
Actual electric fuel pump output depends on the operating conditions and complete fuel system, including:

The adjustable Fuel Pressure Regulator controls fuel pressure in compatible return-style EFI systems. Its 20–120 PSI adjustment range allows the base pressure to be set according to the requirements of the engine, fuel injectors, fuel rail, and engine management system.
The 12V Inline Fuel Pump creates fuel flow through the system. The regulator maintains the selected pressure by directing excess fuel through the return line and back to the EVIL ENERGY 15 Gallon Fuel Cell. The regulator controls pressure; it does not create fuel flow.
Before installation, verify the regulator's port sizes, pressure range, return-line requirements, fuel compatibility, and relationship to the fuel rail and injectors. This regulator should not be assumed to support conventional low-pressure carbureted systems.

The EVIL ENERGY 1060 Aluminum Fuel Line Kit includes 25 feet of 3/8-inch aluminum hard line for custom fuel routing. Its lightweight, bendable construction allows the line to be shaped around the chassis in engine swaps, restorations, racing vehicles, classic trucks, and other custom fuel-system projects.
The pressure ratings apply under specified test conditions. Actual suitability depends on operating pressure, fluid temperature, vibration, installation method, fitting selection, and fluid compatibility.

The supplied adapters connect the AN10 outlets on the EVIL ENERGY 15 Gallon Fuel Cell to the AN6 fuel-delivery components and 3/8-inch aluminum hard line. Selected AN fittings are manufactured from aerospace-grade 6061-T6 aluminum for lightweight, corrosion-resistant connections.
The aluminum fuel line kit includes tools for measuring, shaping, cutting, and preparing the line:

Properly rated PTFE fuel lines may be added where flexible connections are required, but PTFE hose is not included with this kit. PTFE, CPE, and aluminum hard line require compatible fittings and must not be connected using mismatched hose ends.
AN fittings seal at the 37-degree flare surface rather than at the threads. Verify the AN size, thread type, flare condition, tube dimensions, and sealing method at every connection. Do not apply thread sealant to an AN flare-sealing surface.
Fitment and Installation RequirementsThis is a universal custom-installation kit, not a vehicle-specific direct-fit replacement. Before ordering, verify tank clearance, structural mounting strength, feed and return-line routing, ventilation, engine fuel demand, gauge compatibility, electrical requirements, fuel compatibility, and local vehicle modification regulations.
Installation and pressure testing should be performed by someone familiar with automotive fuel systems. Inspect all connections for leakage before operating the vehicle.
