Fuelab_585_RegulatorFUELAB® 585 Series Fuel Pressure Regulators expand the line of Blocking Style (non‐bypass) Regulators like our 555 and 575 Series, in a traditional 4 port package. The main seat assembly can be quickly changed in case of seat damage, such as debris. The seat assembly can be taken apart further to enable o‐ring replacement of the Soft‐Seat design. With dual ‐10AN Inlet Ports and Four ‐6AN Outlet Ports (port spread allows for ‐8AN line size) gives the regulator the ability for extremely high flow rates with a flattened curve for pressure stability through it’s use of a 1.5 inch diaphragm assembly.
