Right now I've got my boot gauge in, but I haven't picked up the fuel pressure gauge. I'm looking for a cover to cover the hole where the 2nd gauge is supposed to go, as I haven't located an older fuel rail w/ a schrader valve, yet.
On the driver side part of the rail, there's a little switch attached by two bolts.. you remove the bolts and the switch, pop the NX block in, then pop the switch on to the NX block, plug one unused hole on the NX block, then run your fuel line from the gauge to the other hole on the NX block.
