Our verdict
Buy EVIL ENERGY if you're doing an LS swap or E85 conversion and want PTFE-lined fuel hardware without paying Aeromotive prices. The 300LPH kits and 20-120PSI regulators handle serious power. Skip it if you need plug-and-play fitment with hand-holding instructions — this is built for DIY builders comfortable assembling AN fittings.

Run E85 through a cheap rubber fuel line and you'll find it cracked and leaking within a season. That's the problem EVIL ENERGY — the performance fuel brand from Shenzhen Bomit Technology — set out to solve. They build PTFE-lined fuel systems, 300LPH pumps, and 20-120PSI adjustable regulators aimed squarely at LS swappers and ethanol-blend builders who need hardware that doesn't dissolve when the fuel chemistry gets aggressive.
EVIL ENERGY operates in a corner of the aftermarket that most big names treat as an afterthought: affordable, ethanol-proof fuel plumbing for the home garage. Shenzhen Bomit Technology isn't a household name like Aeromotive or Holley, and the company keeps its origin story quiet. What's clear from the product catalog is the engineering priority.
Every decision points toward one customer — the builder dropping a junkyard LS into a chassis it was never meant to hold. That person needs a fuel system that works with EFI pressure, survives E85, and doesn't cost more than the engine itself.
The brand answers that with complete kits rather than scattered parts. Instead of sourcing a pump from one supplier, lines from another, and a regulator from a third, EVIL ENERGY bundles the whole fuel path. It's a pragmatic philosophy: solve the actual headache, which is matching components that play nicely together. The result reads less like a glamour brand and more like a workshop that got tired of warranty-claiming corroded fittings and decided to build their own.
The center of EVIL ENERGY's pitch is material science. Standard rubber and nylon fuel lines degrade when exposed to ethanol — E85 is a solvent that breaks down elastomers over time, leaching softened material and eventually weeping fuel. PTFE (polytetrafluoroethylene) doesn't care. It's chemically inert against gasoline, diesel, and ethanol blends alike.
EVIL ENERGY lines a smooth PTFE core inside a CPE (chlorinated polyethylene) and stainless braid outer, giving you ethanol resistance plus abrasion protection and burst strength. In our experience with this construction, the practical benefit is permeation control — PTFE doesn't let fuel vapor seep through the wall, so you don't get that gasoline smell in the garage that nylon-lined hose produces.
The fittings matter just as much. PTFE hose uses a specific olive-and-collar assembly because the slippery liner won't grip a standard barb. EVIL ENERGY's 6AN PTFE fitting kits are cut for exactly this, which removes the guesswork of mixing hose and fittings from different brands.
Pair that with the adjustable 20-120PSI regulator and you cover an enormous range. Carbureted setups want 4-7 PSI; EFI returnless systems run 58-65 PSI. One regulator handles both ends, which is rare at this price and the reason a single kit suits wildly different builds.
EVIL ENERGY covers the entire fuel path and then some. The core lineup is fuel systems, pumps, filters, lines and fittings, fuel cells, and pressure regulators — everything between the tank and the injectors.
Fuel cells come in 5, 10, and 15-gallon configurations, sized for everything from autocross cars to street-strip builds. The 300LPH electric pumps anchor the high-flow range, available as in-tank and external inline versions. Filters span 10, 30, 40, and 100-micron ratings, letting you stage pre-pump and post-pump filtration correctly.
Beyond fuel, the catalog stretches into exhaust systems, ignition coils, oil catch cans, and complete engine swap kits. That breadth makes EVIL ENERGY a one-vendor option for a full LS swap rather than a single-category specialist. The catch cans and coils suggest they understand the build as a whole, not just the fuel side — useful when you'd rather not chase parts across six different brands during a single weekend project.
The standout is the Full LS Swap EFI Fuel Setup with the 300LPH electric pump. This is the product that defines the brand. An LS swap creates a specific problem: the donor engine wants 58 PSI of clean, steady EFI fuel pressure, but the recipient car was probably built for a carburetor running at 6 PSI. You can't just splice it together.
EVIL ENERGY's kit solves that end to end — the 300LPH pump moves enough volume for roughly 600-700 horsepower on gasoline (less on E85, which demands about 30% more flow), the PTFE lines carry it without ethanol damage, and the 20-120PSI regulator dials in exactly the pressure the LS injectors expect.
What stood out to us is the inclusion of the right fittings and a return-line provision in one box. Comparable solutions from premium brands cost noticeably more and still leave you sourcing adapters. The trade-off is that EVIL ENERGY's kits are "universal," so chassis-specific mounting and final routing are on you. For a builder who's already fabricating, that's expected. For someone wanting bolt-in simplicity, it's work.
Here's the honest buyer's question: can you actually install this? PTFE fuel line assembly is not hard, but it's unforgiving. You cut the braided hose cleanly (a cutoff wheel beats a hacksaw), slide the collar on, push the olive into the PTFE liner, and torque the fitting without crossthreading the AN connection.
EVIL ENERGY's documentation is the weak link. Instructions are thin and assume you know AN sizing and assembly technique already. First-timers should budget time for a YouTube tutorial and expect to ruin one fitting learning the process. Once you've done two or three, it's quick.
The 1-year warranty and 180-day return window give real cushion if a component arrives faulty or doesn't suit your build. That return policy is generous for the category and reduces the risk of buying a universal kit you're unsure about.
This brand is built for the DIY performance builder — the person doing an LS swap, converting to E85, or upgrading a tired stock fuel system on a project car. If you're comfortable with a cutoff wheel and AN fittings, EVIL ENERGY gives you premium materials at mid-range prices.
It's also a smart pick for ethanol runners specifically, where PTFE's chemical resistance pays off most. Drag, drift, and autocross builders running 300LPH-class flow will find the pumps and cells right-sized.
Who should skip it? Anyone wanting a fully guided, chassis-specific bolt-in with detailed manuals, and shops billing customer hours who need documented, brand-name components for liability. This is enthusiast-grade gear for hands-on owners, not turnkey convenience.
EVIL ENERGY sits firmly mid-range — well below Aeromotive, Radium, and Fuelab, but above the no-name rubber-hose kits that fail on ethanol. You're paying for PTFE construction and complete kit bundling without the premium-brand markup.
The value math works best on complete kits. Buying a 300LPH pump, PTFE lines, fittings, a filter, and an adjustable regulator separately from premium brands can easily double the cost of EVIL ENERGY's bundled LS swap setup. The current 5% off everything sweetens an already competitive position.
The honest caveat: you trade some refinement and documentation for the savings. If your time is worth more than the price gap and you want zero guesswork, premium brands justify their cost. For builders doing the labor themselves, EVIL ENERGY delivers the better return.
EVIL ENERGY by Shenzhen Bomit Technology is the right call for the DIY builder running an LS swap or E85 conversion who wants ethanol-proof PTFE fuel hardware without premium-brand pricing. The 300LPH pumps, 20-120PSI adjustable regulators, and complete kit bundling solve real fuel-delivery headaches at genuinely competitive cost.
Go in knowing the instructions are sparse and the kits are universal — you'll do some fabrication and learn AN assembly. If that's already your weekend, this hardware earns its place in the build. Take the 5% off, order the complete kit rather than piecing it together, and you'll have a fuel system that outlasts the rubber lines you're replacing.
