Description
Fuel-pressure control in a modified Honda or Acura system starts with a regulator matched to the existing rail and return plumbing. This black CNC-machined billet regulator provides an adjustable setting for a compatible performance fuel system.
AEM provides an interchangeable discharge-orifice arrangement so the regulator can be configured for the fuel pump’s output. It mounts directly on suitable factory or AEM high-volume fuel rails and tracks manifold boost pressure at a 1:1 rate.
