Fuel pressure for 3400.

[greengrandam84]

Just wondering if anyone knows what the stock fuel pressure is on a 3400.

Im looking into getting a fuel pressure safety switch for my N2O setup but im kinda confused about this switch and how it works, and what It should be set at to cut the N2O off. Any help/info would be great!! Thanks !!
