The Edelbrock 17401 rail-mounted fuel pressure regulator fits directly into fuel rails with female -6 ORB ports and arrives pre-set to about 58 PSI for higher-pressure EFI needs. Its compact push-in style and swivel mounting bracket allow orientation to suit tight engine-bay layouts. This non-adjustable rail-mounted regulator is specified as a straightforward addition for Pro-Flo EFI systems where a pre-set, rail-mounted solution is preferred.
