FUELAB® 585 Series Fuel Pressure Regulators expand on 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 exchanged 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 ability for extremely high flow rates with a flattened curve for pressure stability through its use of a 1.5 inch diaphragm assembly.
