can this work
 

okay for my setup now im using a 140 gph pump with -6 line and i just installed a direct port kit and i plan on running about a 200 shot i was thinking of just running another 140 pump and -6 line will this work and also i have some orange regulator from NOS should i use this to regulate the fuel pressure or get something diffrent.

So your talking about runnning a wet flow system instead of running a dry flow system with an FMS. If its a dry flow system, the kit raises fuel pressure in-order to enrich the fuel/oxidizer mixture.

If your talking wet flow then run a seperate line, regulator, and pump, That way its independant of the primary fuel system.
