Default LS1 Intake on 5.3 with returnless fuel system

Does anyone have any pics of this? I have searched since about 11:30 this evening and nothing has really came up.
This is kind of the model the I'm looking at.

The regulator is kind of throwing me off. I'm not going to need one right, because mine is already in the tank? I'm guessing I will have one fuel line coming up towards my engine that will hook onto the driver side rail? I haven't really looked at it yet. Where will I get my fuel for my nitrous? I plan on switching to fuel rails similar to those. Am I headed in the right direction or way off? Any help is greatly appreciated.

I have ran an LS1 intake using a returnless fuel rail. Actually I need to sell it. PM me if interested.
You need this bracket:https://www.performancetrucks.net/fo...d.php?t=357424
There is another write-up on this as well. I think Kano did it. several ways to go but if you want a FAST 90mm I don't think you can use a truck water pump.

yeah you could use aftermarket rails you would just have to have a crossover on one end, plug one end and have an adapter fitting to the factory quick connect.
here is the best pics of mine with a factory LS1 returnless rail.

OK so basically, like that one in the model i'm lookin at...have the hose across the front two ports, plug (say the back passenger port) and my incoming fuel line will go to the back driverside port...Sorry if I don't make any since. It is 3a.m. and I really don't have any idea what I'm talking about since I haven't looked at mine since I got the idea

OK...So lemme see if I'm kinda right.
I'm lookin at fuel rails something like these

I need a hose across the front like what dirt_track has up there, plug the back of the pass. side rail and then my incoming fuel line will go into the back of the driver side rail? Am I close or still oh so far off...

I like the way the front cross over looks. They said you did this on a returnless system. Does it sound like I kinda have an idea how to set this up?
