Just put my new 4.6 the other day In my 93 zj and I'm trying get my fuel pressure up and that web sit with all the stroker info (ajeepthing.com) says to use a FPR from a 96 or later but all the ones I find at the junkyard are the single line rails can someone point in the right direction

Where on that site does it say that? What I see is this:
Fine tune your engine's fuel curve with a Hesco adjustable fuel pressure regulator (FPR).
The fuel pressure can be adjusted to provide the optimum air/fuel ratio.
Part no. for the '87-'90 FPR is HES8790FR
Part no. for the '91-'95 FPR is HES9195FR
There is no adjustable FPR available for '96 and later engines.
The fuel pressure regulator is on top of the pump in the 96+, but it still won't work for you.
Here is another option for the FPR:

24lb/hr injectors with stock 49psi FPR for '96 and later engines
Its saying use those injectors in 96+ vehicles with their FPR
