Question Quick fuel system question

twin turbo 6.0L LS, in tank pump capable of 900hp. I would like to run the fuel lines so that there is no crossover on the front of the of the rails so the way I would like the run the system is as follows:

tank---->filter----->regulator----y fitting----->to each rail. Then dead head the rails
Then use the regulator return to go back to the tank. Regulator will be mounted on the firewall just before the rails

Is this acceptable when thinking about making 700-800hp assuming I've selected the right pump, injectors etc or do I have to run in one rail and out to the other like some setups I've seen?

Thanks

regulator should be between or after the rails. each injector that uses fuel causes pressure to drop which is information you need to see, not pressure before the rails.

You can dead head to the rails at 700-800 horsepower without much of an issue. The regulator becomes a flow restriction when placed before the rails. As long as its up to the task, it'll be fine.
