Since your looking at buying lines and a regulator, i would just pick up a set of rails as well and build a return style system. Go with -8 feed and -6 return, and put the regulator under the hood. It will cost you a little more but you will have an awesome fuel system that will feed all the power your TT setup will make with no worries whatsoever. Just my .02

 

If someone made rails for the truck intakes i would. and i dont have any access to have aluminum welded so adapting car rails is out of the question.

 

Any of the vette or aftermarket rails will work. You just need to modify the mounts so they are the correct height to fit the injectors of your choice. The rest is pretty east to do.

 

If the setup i described in my diagram will support 700 -800 max im gonna go that route. its easy and i dont ever plan on going any higher than 800 hp. If -6 line wont support that kind of power someone please correct me.
