Is the Satria Neo using a returnless fuel system or return type? Either way you don't need to change the fuel rail to install a AFPR.

normally efi with fuel return line no need to change fuel rail, but aftermarket fuel rail increase the flow capacity for future mods or higher HP mods later. It all depends on your target.

There's 2 ways to install a FPR on a returnless system
1. You install the FPR at the fuel pump there before going to the fuel rail.

2. You change the fuel rail to a return type, install the FPR at the engine bay and you pull a return line from the FPR and hook up to the stock return port at the fuel pump assembly. Then you remove the internal constant pressure valve inside the fuel pump assembly. Your new adjustable FPR you no need to connect the vacuum reference just bock it. You put in on Dyno and you increase the FPR bit by bit to get the best result. How to get a base FP figure is you look at the stock constant pressure valve It is usually etched at the side of the pressure valve body.

Both method has it pros and cons and also your budget. I went with the 2nd method because I wanted easy access and able to see the readings and also in future if I wanted to hook up a FP gauge it's lot less work.

If your fuel system is already a return type then very very easy just change the FPR kaotim....no need hassle.
