Aeromotive Universal 3-Port Bypass Fuel Pressure Regulator - 3/8in NPT

The Aeromotive Universal Bypass Fuel Pressure Regulator is built for EFI and carbureted setups in street and strip applications. Featuring 3/8in NPT ports and a true bypass design, it helps maintain stable, consistent fuel pressure under changing load. Base pressure is adjustable from 3–20 PSI with the standard spring (installed) or 20–60 PSI with the included high-pressure spring. Suitable for regulating fuel pumps from 100–250 GPH, it’s a versatile solution for performance fuel systems, including boost-referenced configurations with a 1:1 rise rate.

Key Features

  • 3/8in NPT ports for flexible plumbing
  • One inlet / three outlets to suit different fuel system layouts
  • Bypass regulator design for dynamic pressure control
  • Boost reference 1:1 fuel pressure rise capability
  • Two springs: standard installed + high-pressure included
