Product Details

The Holley 12-846 HP Billet EFI Bypass Fuel Pressure Regulator delivers precise fuel pressure control for high-performance EFI systems with return lines. Designed for use with electric fuel pumps, this bypass-style regulator is adjustable from 15-65 PSI to accommodate a wide range of fuel system requirements.

Key Features:

  • Adjustable fuel pressure range from 15-65 PSI for precise tuning
  • Billet aluminum construction with black anodized base and clear anodized top
  • -8 AN O-ring inlet and outlet ports with -6 AN O-ring return port
  • 1/8" NPT gauge port for pressure monitoring
  • Includes fitting for manifold vacuum/boost reference
  • Mounting bracket included for easy installation
  • Bypass design for use in systems with return line back to fuel tank

This regulator is engineered specifically for use with electric fuel pumps, including Holley HP in-line fuel pumps and other high-pressure electric pumps. The bypass configuration ensures consistent fuel pressure while returning excess fuel to the tank, making it ideal for EFI applications requiring precise fuel delivery. The manifold reference capability allows the regulator to maintain proper fuel pressure under varying vacuum and boost conditions.

I was satisfied with my purchase. It was difficult getting a high gloss, but I think that was because I didn't sand the surface smooth enough. Oh well! I may sand lightly and reapply.

seems like good job! thanks
