Description: Dynamic flow and rock steady pressure make this regulator perfect for naturally aspirated or carbureted blow-through applications. The A2000 Bypass Regulator provides unmatched boost reference and high flow capacity. Compatible with any high volume electric or mechanical fuel pump. Adjustable from 2-20 PSI. Bypass design provides the ultimate, dynamic fuel delivery system. (Requires AN-10 return line.) Fuel pressure rises on a 1:1 ratio when referencing boost. ORB-10 inlet and return ports. P/N 13202 provides (4) ORB-08 outlet ports.?Note: High pressure, boost reference applications require high volume, high pressure fuel pumps. EFI capable, electric or mechanical pumps like the Aeromotive Pro-Series (P/N 11102), Eliminator (P/N 11104), or Belt Drive Fuel Pump (P/N 11105) are strongly recommended.
