Fuel pressure regulator plumbing?

if that is a holley regulator. 803...screw it up reduces the pressure....just installed new regulator on a Duster....instructions said to turn clockwise to increase pressure...and they are preset at 6 psi....which is what mind showed on start up...


The regulator comes from Holley with the regulator pressure preset (see table). However, for individual requirements, it may be readjusted. Loosening the regulator locknut and turning the adjustment screw clockwise increases the pressure. Decrease pressure by turning the adjustment screw counter-clockwise.
