How do you adjust the fuel pressure on this thing? I see the tiny hole on the regulator and assume that's it. It's just so tiny, I don't know what I would use to adjust it. Also, does anybody know what the factory fuel pressure is set to on the Holley 670?
Thanks

 

thats not it, i wish i was on my computer i would show you a pic of it . on cyl thing that comes up in the back of the unit that is inbetween the injectors there is a stamped steal cap over the screw and you have to remove that to ajust the fp. i drilled it out but watch out you dont mess up the bolt underneath

 

here is a pic i could not find a direct pic but its on top and right behind the hold down bolt

Thank you for the help guys.
It's kinda stupid for holley to advertise it as readily adjustible, when indeed it's not quite that simple. Though it doesn't seem too hard to do....I guess I'll find out soon.....
