EVIL ENERGY Fuel Filter Regulator for LS Swap C5 - 58 PSI Fixed with 10‑Micron Filter

EVIL ENERGY's Fuel Filter Regulator is an all-in-one 58 PSI fuel pressure regulator and 10-micron filter designed to simplify LS-swap EFI setups for C5 and other LS-based engines.

If you're converting a vehicle to an LS-based EFI system or upgrading fuel management on a 1999–2014 Chevrolet V8 (4.8L/5.3L/6.0L), this compact unit combines pressure regulation and filtration in a single package to save space and reduce plumbing complexity. Built to handle gasoline, diesel, E85 and various fuel blends, it maintains a stable 58 PSI output and keeps contaminants out of the fuel rail with a fine 10-micron element.

How does this unit control fuel pressure for an LS swap?

The regulator uses an internal bypass design to hold fuel output at a consistent 58 PSI, which aligns with many LS EFI tuning setups. That steady pressure ensures predictable injector performance and simplifies calibration during the conversion process.

• Fixed 58 PSI regulated output for stable injector flow.
• Internal bypass reduces external plumbing and leak points.
• Designed to install in the engine compartment for even pressure distribution.

Will the EVIL ENERGY filter protect my injectors and pump?

Yes — the built-in 10-micron filter element captures fine particulates before they reach injectors or the high-pressure pump, reducing wear and potential clogging. Cleaner fuel helps maintain consistent spray patterns and longevity of fuel-system components.

• 10-micron filtration removes small debris that can damage injectors.
• Integrated design keeps contaminants away from the rail and pump.
• Compatible with common automotive fuels to suit varied builds.

Is this regulator compatible with my vehicle and the fuels I plan to run?

The unit is specified for LS-based Chevrolet V8 engines from 1999–2014 (4.8L/5.3L/6.0L) but can be used in many LS-swap projects where a 58 PSI regulated feed is required. It accepts gasoline, diesel, E85 and other fuel blends, offering flexibility for performance or alternative-fuel applications.

• Fitment: 1999–2014 Chevy LS-family V8 engines (4.8L/5.3L/6.0L).
• Fuel types: gasoline, diesel, E85 and compatible blends.
• Ideal for C5 swaps and general LS EFI conversion installations.

How do I install and position the regulator for best results?

EVIL ENERGY recommends mounting the regulator in the engine compartment so fuel pressure is evenly distributed and heat exposure is manageable. Its compact form reduces plumbing runs, and the integrated filter means fewer separate components to locate and plumb.

• Mount in engine bay near fuel rail for balanced pressure delivery.
• Use proper-rated fuel lines and fittings compatible with chosen fuel type.
• Inspect and replace the filter element per service intervals or after contamination events.

Who is this for: Builders converting older cars to LS EFI, C5 owners upgrading fuel management, and anyone needing a compact, reliable 58 PSI regulator with fine filtration. If you want to reduce external plumbing, protect injectors and pumps from debris, and support gasoline, diesel or E85 setups in LS-based engines, this EVIL ENERGY unit provides a space-saving, serviceable solution.
