EVIL ENERGY 6AN Fuel Line Kit — 25ft Braided Hose with 58psi LS‑Swap Regulator & 10µm Filter

EVIL ENERGY 6AN Fuel Line Kit with LS Swap regulator is a complete, high-pressure braided fuel hose system that includes a 58psi regulator and filter for reliable EFI and LS-swap installations.

This kit is designed for vehicle builders and tuners who need a ready-to-install 6AN fuel line system compatible with gasoline and diesel (not for E85/ethanol). It combines a CPE rubber inner hose, 304 stainless braid and durable aluminum swivel fittings to create a flexible, high-strength feed line suitable for EFI conversions, LS engine swaps, and many aftermarket fuel injection projects. The assembly includes a built-in 10-micron filter element and a 58psi fuel pressure regulator with an internal bypass to protect your engine from contaminants and pressure spikes while maintaining stable fuel delivery.

How does this kit handle fuel system pressure and safety?

The EVIL ENERGY hose is rated for demanding conditions: a maximum working pressure up to 750 psi and a bursting pressure around 2250 psi, while the regulator maintains a stable 58psi output. The braided construction resists expansion under pressure, and the internal filter captures debris before it reaches injectors or pumps.

• Working pressure: 750 psi; burst rating approximately 2250 psi.
• Integrated 58psi LS-swap regulator with internal bypass for pressure control.
• 10-micron built-in filter element to trap particulate contaminants.
• CPE inner tube and 304 steel braid resist fuel swelling and abrasion.

What fittings and hose lengths are included for installation?

The kit is packaged as a complete plumbing solution so you can route and attach fuel lines without sourcing additional adapters. Included swivel hose ends and adapters let you connect to common fuel rail, pump, and return fittings found in EFI and LS-swap applications.

• 10 swivel 6AN hose ends: 4 straight, 2×45°, 2×90°, 2×180° for flexible routing.
• Adapters: 6AN to 3/8", 6AN to 5/16", and a 6AN to 3/8" 90° fitting.
• Hose clamp separators (2) plus a wrench for assembly.
• Braided fuel hose length included: approximately 25 feet; inner diameter 0.31", outer diameter 0.56".

Which fuels and environments is this hose suitable for?

The hose construction — CPE inner tube with nylon and stainless braid — supports most liquid hydrocarbons used in street and race applications, but it is not rated for ethanol blends like E85. Temperature and chemical resistance make it appropriate for typical engine bay conditions.

• Compatible with gasoline and diesel; not compatible with E85/ethanol fuels.
• Temperature range: -22°F to 248°F for engine compartment use.
• Outer nylon braid resists abrasion and UV exposure; 304 steel braid adds strength.
• Aluminum alloy fittings reduce corrosion and weight compared with steel.

How does the built-in filter and regulator protect my engine?

The regulator controls downstream pressure at 58psi to match many LS and aftermarket fuel rails, while the internal 10-micron filter removes small particulates that can damage injectors and pumps. Together they help maintain consistent fuel delivery and reduce the risk of clogging in sensitive EFI components.

• 58psi regulated output suited for many LS-swap fuel rails and injectors.
• 10-micron filter element captures dirt and rust before the pump or rail.
• Internal bypass prevents overpressure and maintains flow during heavy demand.
• Serviceable design simplifies filter replacement during maintenance.

Who this kit is for: This EVIL ENERGY 6AN braided fuel line kit is aimed at automotive enthusiasts, professional installers, and DIY mechanics installing EFI conversions or LS engine swaps who need a complete, high-pressure, and flexible fuel plumbing solution. It's a practical choice when you want pre-sized hose, multiple swivel fittings, adapters, and a regulated, filtered fuel supply in one package — provided your build uses gasoline or diesel (avoid E85) and requires a 58psi regulator setting.
