Fuel Pressure Regulator EVIL ENERGY Adjustable 20-120psi Bypass Kit

Description

Product Overview

The EVIL ENERGY Fuel Pressure Regulator is engineered to deliver precise fuel pressure control for a wide range of electronic fuel injection (EFI) applications. Constructed from high‑grade painted metal and featuring a robust nylon‑braided fuel line, the regulator provides durability against corrosion, vibration, and temperature extremes commonly encountered in automotive environments. The unit includes a pre‑installed spring that covers a pressure range of 20‑75 psi, while an optional replacement spring expands the range to 75‑120 psi, allowing users to fine‑tune performance to match specific engine requirements. Integrated into the design is a NPT‑threaded pressure gauge port, enabling real‑time monitoring of fuel pressure without the need for external instrumentation. The package also supplies a comprehensive set of fittings—AN10, AN6, and AN8 adapters—along with an AN10 port plug, sealant tape, an allen key, and a replacement spring, ensuring that installers have all necessary components at hand. Dimensions of 9.14 × 7.13 × 3.42 inches and a weight of 1.79 lb make the regulator compact enough for tight engine bays while maintaining structural integrity.

Usage

This regulator is ideal for performance enthusiasts, tuners, and professional mechanics who need reliable fuel pressure management across a variety of gasoline and E85 fuel blends. It fits most vehicle EFI systems, making it suitable for daily drivers, race cars, and off‑road trucks alike. The adjustable pressure range allows users to optimize fuel delivery for high‑output engines, improving throttle response and overall power output. Installation is straightforward for those familiar with fuel system work; however, professional installation is recommended to ensure proper sealing of the NPT gauge port with thread sealant tape. The regulator’s compatibility with both gasoline and E85 (excluding diesel) expands its utility for owners seeking to experiment with alternative fuels or to comply with regional fuel standards. Its robust construction also makes it a reliable choice for harsh environments, such as desert rallies or heavy‑duty towing applications, where fuel system stability is critical.

FAQ

What vehicles are compatible with this fuel pressure regulator?

The regulator fits most gasoline and E85 EFI systems found in passenger cars, light trucks, and performance vehicles. It is not compatible with diesel fuel systems.

How do I adjust the pressure setting?

Turn the set screw on the top of the regulator clockwise to increase pressure or counter‑clockwise to decrease it. Use the included gauge to verify the desired pressure range.

Is professional installation required?

While experienced DIYers can install the regulator, we recommend professional installation to ensure proper sealing of the NPT gauge port and correct torque of the AN fittings.

What does the replacement spring do?

The replacement spring expands the adjustable range to 75‑120 psi, allowing higher pressure settings for high‑performance engines that require more fuel flow.

Can I use this regulator with E85 fuel?

Yes, the regulator is designed to work with gasoline and E85 blends. However, the nylon‑braided fuel line is not compatible with E85; a compatible line should be used if E85 is the primary fuel.
