EVIL ENERGY 6AN Fuel Line Kit with LS Swap Fuel Filter Regulator
This 6AN braided fuel line kit supports LS swaps and EFI conversions. It includes a fuel filter regulator with a 58 PSI output, helping maintain consistent fuel pressure to the engine. The hoses are compatible with gasoline and diesel, though not designed for E85. Best for: builders needing a compact, integrated fuel delivery solution with a built-in regulator. Limitation: not suitable for ethanol-rich fuels.
LS Swap Motor Mounts Adapter Plates – Small Block Kit
Mejiao’s adapter plates enable bolting an LS engine into vehicles that originally had small block Chevy setups. The design shifts the crankshaft centerline for improved performance and alignment. Best for: users swapping LS into non-LS original small block chassis. Limitation: aluminum plates require precise fitment and may need shop alignment for best results.
ICT Billet LS Turbo Alternator and Power Steering Bracket Kit
Designed to relocate the alternator and power steering pump toward the engine centerline, this USA-made billet aluminum kit improves turbo header clearance. Best for: builds requiring tighter spacing around sleeves and pulleys. Limitation: may require additional brackets or spacers for certain LS variants not listed in compatibility notes.
ICT Billet LS Truck Power Steering Bracket Kit Swap
Specifically crafted for LS trucks and SUVs, this billet aluminum bracket sits with OEM-style fitment. It supports compatibility with LS3 and L99 Camaro crank pulleys and keeps the PS pump aligned with factory tolerances. Best for: trucks and SUVs needing a robust PS mounting solution. Limitation: compatibility may vary with non-standard crank pulley setups.
EVIL ENERGY PTFE 6AN Fuel Line Kit
This 26-foot PTFE fuel line kit uses 6AN hose with PTFE material, offering excellent chemical resistance and high pressure. The line is rated for up to 1,500 PSI working pressure and 4,500 PSI bursting pressure, suitable for high-performance applications. Best for: long, complex runs in LS EFI systems. Limitation: longer length means more routing considerations and potential cost for installation hardware.
Buying Guide
How to choose the right LS swap kit pieces for a boat or street vehicle:
- Fuel system compatibility: Choose lines and regulators that match your fuel type (gasoline, diesel, or E10/E15 blends) and temperature exposure.
- Pressure and reliability: For LS swaps, ensure regulators and hoses meet your engine’s pressure needs and are rated for marine environments if used on watercraft.
- Fitment and mounting: Adapter brackets and mounting kits should align with existing mounting points; wrong alignment can affect accessory belt routing and sensor positions.
- Material and durability: Billet aluminum parts offer stiffness and precise tolerances; PTFE hoses provide chemical resistance and high-temperature tolerance.
- Installation needs: Some kits require machining or professional installation; verify whether you’ll need a shop for alignment, pulleys, or brackets.
- Routing considerations: Complex hose routing may demand longer lines or extra clamps, especially in engine bays with turbo setups or marine installations.
FAQs
Q1: Are LS swap brackets universal for all LS engines?
A1: Most brackets are designed to fit a range of LS variants, but verify compatibility with your exact engine model and accessory layout.
Q2: Can these fuel lines be used with ethanol blends?
A2: Some lines are rated for gasoline and diesel but explicitly exclude E85; select ethanol-compatible options if needed.
Q3: Do these kits include all mounting hardware?
A3: Many kits include essential bolts and fittings, but some may require additional hardware depending on the vehicle and engine configuration.
Q4: Is professional installation recommended?
A4: For most LS swaps involving multiple brackets and fuel lines, professional installation is advised to ensure proper fitment and safety.
Q5: Does the fuel regulator require separate tuning?
A5: The included regulator maintains a baseline 58 PSI output; tuning may be needed for specific engines or turbo setups.
Q6: Are these kits suitable for marine use?
A6: Some components may be marine-rated, but confirm water exposure suitability and corrosion resistance before installing on boats.
