If you have a billet (newer style) fuel rail, tapp it onto the end of the fuel rail opposite the fuel intake (by the fpr). If you don't you need to drill and tapp the banjo bolt on the top of your fuel filter, put a 90 degree brass npt fitting on there and then install the fuel pressure cut off on there. DON'T run without it, there is no way you can react fast enough if the fuel pressure drops. If you need the tapp sizes post again and i'll give you the part numbers. I also suggest getting an msd rpm activated switch, that way the nitrous only comes on over 3000 rpm and can be cut off at say 200 rpm before your rev limiter, that way you will never spray before the safe rev limit for the kit and you wont run out of fuel if you miss your shift point (the stock rev limiter cuts off fuel at the redline or so).
