Dual in take pumps with razors kit dual nozzle kit

Question
Do i need to run my second fuel pump with a dual nozzle system? I typically run 25lbs of boost on the street. Can is a low 11 hight 10 second car. I know this is a loaded question but, Im worried I will pump to much 93 and not enough Meth.

Thanks ,
Chris

Your injector duty determines how much fuel the engine gets
as long as the fuel pressure doesnt spike over the 1:1 ratio the motor wont see any more fuel with two pumps than it would with one ,

stage the second pump to come on above the point where fuel pressure will be with both pumps running.
this is done with a hobbs switch that turns the second pump on based on boost pressure
i had no problems with dual pumps and a stock return lines turning the second pump on at 12psi of boost.

Thanks for the info. I found out that my fuel pressure gauge went bad and was giving me some bad readings. My static fuel pressure was 34psi. I bought a new gauge installed it and bumped the pressure up to 40psi and went for a spin. A/R @ 25psi is 10.3....So all is good. I did adjust my second fuel pump to come on around 15psi. Seems to like it.

Thanks
