Who Needs This LS Swap Fuel System Kit?

Our products are designed for three main types of automotive enthusiasts:

Core Components for Every Application

Regardless of your project, the Evil Energy LS swap fuel system covers all bases:

Fuel Delivery: The LS swap fuel pump is the heart of the operation. Whether you choose an in-tank or external setup, our LS fuel pump kit ensures your injectors receive a steady 58psi.
Fluid Transfer: We use premium braided LS fuel lines (Stainless or Nylon). These fuel lines for LS swap are superior to rubber, offering resistance to heat and chemical corrosion.
Integration: Connecting a modern LS fuel line to a vintage LS swap gas tank can be tricky. Our inclusive LS fuel line kit comes with the necessary LS fuel line adapter and regulator to make this 'plug and play.'

Solving Common Installation Challenges

Our LS fuel system kit is designed to overcome the most common hurdles in engine swaps:

Pressure Regulation: The included filter/regulator in our LS swap fuel line kit manages pressure automatically, simplifying your LS fuel system layout.
Adaptability: With our universal fuel line kit for LS swap, you can custom route your LS fuel lines away from headers and moving parts.
Connection: No special tools are needed to use our LS fuel line adapter kit. It converts factory hard lines to AN fittings instantly, securing your LS1 fuel line.

Preform Carb

Better than I expected, the EVIL ENERGY carburetor runs well right after starting, and the polished surface looks finely finished, not like it was unevenly polished by a buffing wheel.

Great for country roads

I live in rural Montana where deer are a real hazard. These lights give me that extra reaction time. Can see at least 50% further than stock halogens.

Great bright light

Amazing lights! Beam is bright and wide. The price can’t be beat. Handles heat great, the separate block handles heat better than the all in one. I have ran multiple brands, my friends run the Ultra 3 and these blow them out of the water.
