IMPCO Regulator Model PJ , Positive Pressure, Two Stage Regulator , Natural Gas , Positive Flow Up To 80 Hp
Model PJ is a positive pressure, two stage regulator. It is designed for positive pressure Natural Gas fuel systems where liquid vaporization and engine coolant heating are not required, however, additional fuel temperature and mixture stability may be gained through the use of engine coolant.
This regulator is able to provide positive flow in applications up to 80 hp (59.7 kW). Fixed regulators can be converted in the field to adjustable with the AC1-74 kit. Fixed pressure regulators are preferred in applications that are not subject to fuel quality variations or to deter unauthorized tampering. There is a primary pressure test port and “left” or “right” fuel outlets.
