A1000 Bypass Regulator was designed for use with our A1000 Fuel Pump or similar style EFI pumps in a carbureted application. This regulator is perfect for naturally aspirated or’blow-through’ supercharged engines. Base fuel pressure adjustable from 3-15 PSI. (1) ORB-10 inlet port and (1) ORB-08 return port. P/N 13204 provides (2) ORB-06 outlet ports and 1/8′ NPT gauge port. Fuel pressure rises on a 1:1 ratio when referencing boost. Ideal for converting from fuel injection to carburetion using the stock, in-tank pump. EFI conversions will require a larger-than-stock return line for proper low pressure control.
