Universal Aluminum Fuel Regulator with AN8 Feed and AN6 Return, 3-70 PSI

Universal Aluminum Fuel Pressure Regulator with AN8 Feed & AN6 Return — a versatile, high-performance regulator designed to stabilize fuel pressure across a wide range of engines and fuels, including E85 and other alcohol blends. By keeping fuel pressure steady, it helps maintain optimal injector spray, improve throttle response, and promote more efficient fuel use under varying driving conditions.

Crafted from CNC-machined aluminum billets, this regulator delivers rugged durability, excellent high-temperature and high-pressure resistance, and corrosion resistance for long-lasting performance in demanding environments. It includes a 0–160 PSI gauge for precise monitoring, so you can dial in the perfect fuel curve with confidence. The unit features AN8 feed and AN6 return lines, providing reliable connections for performance-grade fuel systems.

The regulator is adjustable from 3 to 70 psi. It ships with three interchangeable springs (3–20 psi, 20–45 psi, 45–70 psi) and a knob to fine-tune the pressure. For settings within the 20–45 psi range, the factory-installed spring is the proper choice. If you need 3–20 psi or 45–70 psi, back out the pressure adjustment set screw, remove the four cover screws and cover, swap the top spring, and reassemble. The kit can also be configured for a single feed by capping off one feed line if needed.

This universal regulator is ideal for performance builds, street cars, and any setup requiring stable fuel pressure and accurate fuel delivery. It’s compatible with E85 and other alcohol-based fuels, helping maintain consistent injector volume and potentially reducing fuel consumption when tuned correctly. All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.

Benefits & Tips

• Maintains stable fuel pressure across RPM and load changes, improving throttle response and fuel economy, especially with ethanol blends.
• Flexible tuning with three springs: factory 20–45 psi works out of the box; swap springs to reach 3–20 psi or 45–70 psi as needed.
• Use the included 0–160 PSI gauge to monitor pressure in real time and fine-tune your fuel curve for your engine’s needs.
