There is NOTHING MAGIC about a regulator... it has a
hole and a spring to let the set pressure by.. I dont
care for the NON return style reg due to fuel pressure
fluctuation and I run a return style(I have for 20
years now).. yes at one time I did run the cheapo
holley reg but then I started working in the fuel
lab and seen the benefits of the return style systems
and have been that way since
