PQY Adjustable Fuel Pressure Regulator Kit — 3-70 PSI, 6AN Return & 6AN Feed

Premium fuel pressure control for EFI systems

The PQY Adjustable Fuel Pressure Regulator Kit is designed to empower a wide range of EFI builds. With a versatile 3 to 70 PSI range, this regulator supports modern blends including E85 and other ethanol-containing fuels. The precision-machined billet aluminum body delivers a solid, tactile feel as you tune the system, while the compact form keeps installation neat in tight engine bays.

Whether you are dialing in a street setup or preparing for a performance upgrade, this kit offers adaptable control without complicating your routing. The included gauge and reference line help you monitor and reference pressures as you fine-tune for your fuel map, boost level, and overall fuel delivery strategy. The return-style design provides a familiar feedback loop that works as a drop-in replacement for many standard regulators, making it easier to upgrade without reworking the entire line system.

What you get and how it helps

• Regulator body with 6061-T651 billet aluminum and CNC-machined finish for durability and consistent actuation.

The rugged build, combined with multiple port options, supports straightforward integration into many EFI systems while allowing room to experiment with different fuel strategies. It is a strong candidate for enthusiasts looking to upgrade their fuel pressure control without sacrificing reliability or compatibility.

Tips for installation and use

• Ensure all fittings are tightened to spec and check for leaks after initial startup.
• Use the gauge to verify the pressure after installation and during tuning sessions.
