Adjustable from 2 to 20 psi, the A2000  Fuel Pressure Regulator is designed for use with Aeromotive's Drag Race Fuel Pump. The vacuum boost port makes it ideal for high-volume electric or mechanical fuel pumps of any kind where rock-steady pressure control is desired. Also perfect for blow-through carb applications with a turbo or centrifugal supercharger. Boost reference and high-flow capability are unmatched.

  • Bypass design provides the ultimate dynamic fuel delivery system
  • Four -8AN O-Ring Outlet Ports
  • -10AN O-Ring Inlet and Return Ports
  • Fuel pressure 1:1 ratio when referencing boost
  • Alcohol compatible

Note: High-pressure boost reference applications require high-volume, high-pressure fuel pumps. EFI-type electric or mechanical high-volume pumps with no internal bypass valve are recommended for best results.
