EFI Wiring Harness

This comprehensive kit includes: 

• 5/10/15 Gallon Fuel Cell Tank
• 20-75PSI&75-120PSI fuel pressure regulator
• 300LPH high flow fuel pump
• 6AN 20FT CPE/PTFE Durable fuel lines (optional fittings)
• 10&100-micron fuel filter
• 50mm Fuel Filter Mounting Bracket*2
• 60mm Fuel Filter Mounting Bracket*1
• necessary fittings for easy installation. 

Durable Construction: Precision-machined 6061-T6 aluminum alloy, corrosion-resistant and heat-tolerant (withstands harsh engine bay conditions), ensuring long-term reliability.

EFI System Compatibility: Fits most vehicles' electronic fuel injection (EFI) systems; maintains stable fuel pressure for optimized combustion, performance, and fuel economy.

Fuel Compatibility: Works with gasoline, E85, and alcohol/ethanol; not compatible with diesel fuel; note: nylon braided fuel lines are not E85-compatible (use PTFE-lined hoses for E85).

Bypass Return Design: Prevents pressure spikes during acceleration, boost, or high-load scenarios, protecting fuel injectors and rails from damage.

All-in-One Kit: Each variant includes essential components (fuel pressure regulator, pressure gauge, fittings, sealant tape, tools like Allen keys); no extra purchases needed for standard installation.

Easy Installation & Tuning: Adjust pressure via top set screw (clockwise = increase, counterclockwise = decrease); use thread sealant tape on NPT gauge port to avoid leaks; professional installation highly recommended (especially for high-pressure variants).

Three-Layer Construction: Our fuel lines are constructed with a triple-layer material for unparalleled performance and protection. The innermost layer is made of PTFE for maximum chemical resistance, a braided stainless steel layer for strength and durability, and an outer nylon layer for added abrasion resistance and protection.

Multiple Sizes: We offer our fuel lines in 4AN, 6AN, 8AN, and 10AN sizes, catering to the diverse needs of various fuel delivery systems.

Fitting Types: Our kit includes a variety of fittings at 0°, 90°, 45°, and 180° angles, ensuring versatility and flexibility during installation, allowing for custom routing in tight or complex spaces.

Precision Fit and Leak-Free Performance: The combination of the PTFE inner layer and the high-quality aluminum hose ends ensures a precision fit and leak-free connection, even under extreme pressure, providing a safe and reliable fuel system.
