The BLOX Racing adjustable fuel pressure regulator (FPR) is an affordable and easy-to-install alternative to those complicated and expensive aftermarket units. This billet aluminum piece installs on to the factory fuel pressure regulator, turning it into an adjustable unit, allowing users to properly tune the air / fuel ratio. This is ideal for any aftermarket products requiring a bump in fuel pressure. It is designed to work with the factory fuel rail.
Key Features
- Wide Adjustment Range: 10-100 PSI tuning matches base maps to boosted or high-flow injector setups for reliable fuel atomization.
- Billet Aluminum Body: CNC-machined 6061-T6 aluminum with black anodized finish withstands high heat and fuel corrosion.
- Full Hardware Kit: Includes mounting bracket, jam nuts and adapters for plug-and-play setup on compatible chassis.
- Viton Diaphragm: High-temperature Viton seal handles EFI pressures and chemicals without leaking or degrading.
- Mount inline on fuel pressure return line after the fuel rail.
- CNC billet 6061-T6 aluminum housing with black anodizing and Viton internals for fuel resistance.
