After talking to people not involved in the ls1 world I'm confused. I have a dual Nozzle set-up but not sure the best place to plum into the fuel system??

Looking at alot of install pics and looks like everyone is tapping into the end of the fuel rail where the pressure test valve is?? Is that safe doesn't that rob fuel from the injectors??

and isn't that a regulated fuel line isn't better todo before fuel regulator??

I'm no pro so easier is better but I want to do it saftly

Thanks in advance

 

You can do it either way. The fuel comes into the rails in the center of the driverside and you will take it off the forward end so it won't rob the rest of the system. I ran my dual staged MAF kit off the rails without a problem.

 

Just attach the fuel line to the test port on the rail, you won't have any problems with it that way. Probably sounds dumb, but remember to remove the core of the test port(looks like a bicycle valve stem). You would be amazed at how many people don't and wonder why they aren't getting any fuel out of the solenoid.
