Product Compare

The EVIL ENERGY Fuel Pressure Regulator Kit is purpose-built for low-pressure carbureted fuel systems, making it ideal for classic muscle cars, hot rods, motorcycles, generators, and other carbureted applications. Constructed from lightweight yet durable 6061-T6 aluminum with a corrosion-resistant finish, it provides stable and precise fuel delivery with an adjustable pressure range of 4.5–9 PSI. Designed to help prevent carburetor flooding, fuel starvation, and inconsistent performance, this regulator ensures smoother throttle response and reliable engine operation.

Equipped with versatile ports (1/8IN NPT gauge port + two 3/8IN NPT feed/return ports) and compatible with gasoline, E85, diesel, and ethanol/alcohol (note: nylon braided lines are not E85-compatible), this kit adapts to most carbureted setups. It includes everything needed for a professional, hassle-free installation: 1 fuel pressure regulator(Vacuum or Non-Vacuum), 1 5–12 PSI gauge (for real-time pressure monitoring), 1 mounting bracket, 3 3/8IN NPT to 6AN Fittings or 3/8IN NPT to 3/8IN Brab Fittings, 1 Allen key, sealant tape, and all required self-tapping/cheese head screws.

Whether you’re restoring a classic car or maintaining a small carbureted engine, this kit eliminates the need for separate part purchases and ensures consistent fuel pressure—keeping your engine running efficiently and extending its lifespan.
