this kit includes the fuel pressure regulator with the lines that feed the ls1 style fuel rails and attached right to your existing metal lines in your 3rd gen making a fuel line conversion as easy as pie.. i bought it from hawks thirdgen and i can use it cuz i am building an lsx bowtie block with a lot of horses and need a better fuel pump and bigger lines and a different regulator (i thought this would work) i wanted to return it but those rapists charge a 25 percent restocking fee. i paid about 400 for this thing so i am gonna give them 100 bucks i think not... you can have it for 380 including shipping.. once again never installed so it is brand new untouched.. in the box from hawks call nate 508-523-1627
