zex dry system

[onebadassws6]

Hey guys im tring to put a 50 shot on my 99 ws6 and i have a zex kit... i need the vacume lines that come off the fuel pressure regulator but what i thought is the fuel pressure reg does not have vacume lines comming off it....and the kit needs them isnt the fuel reg on the fuel rail on the drivers side?

that sounds like a LT1 setup. the LT1 uses a regulator with vacuum lines. the LS1 doesn't use it. the n2o goes through the MAF and adds fuel that way.
