Description
xFlexible fuel pressure control for modern EFI setups
The PQY Adjustable Fuel Pressure Regulator Kit is designed to provide precise control over fuel delivery for most EFI systems that run on gasoline, E85, or ethanol blends. It is not intended for diesel engines, and when using E85 with certain hose materials, nylon braided lines may not be compatible.
Key features at a glance
- Wide pressure range with four replacement springs to dial from 3 to 110 psi; the kit ships with a 60-90 psi preinstalled spring for immediate tuning.
- Durable billet aluminum construction with AN10 feed port and AN6 return port, plus a 1/8 inch NPT gauge port and a vacuum boost line connection.
- Easy top bolt adjustment for fine tuning; if you only need a single feed port, an end cap is included for a simplified setup.
- Complete kit includes regulator, gauge, four springs, sealant tape, Allen key, multiple fittings, and port adapters for flexible installation.
Port mapping and compatibility
The regulator uses standard AN style ports for reliable connections and is suitable for EFI systems running gasoline or ethanol blends. Diesel lines are not supported. When installing the NPT gauge port, apply thread sealant tape to ensure a proper seal.

The gauge port lets you monitor pressure while testing tuning changes, helping you explore different fuel delivery scenarios safely.
