Trying to understand a few things...
I have a 91 Camaro that i'm putting a LS1 into and i'm going to be using a LS1 plastic gas tank. I already took care of the fuel gauge problem, now i'm trying to understand how the LS1 fuel system works. I have the tank and sending unit but no lines. I know their are 3 lines that go from the tank, but only 2 go to the engine compartment. Also after the filter is a "T" connection. Is that the return line that goes back to the regulater?? picture of section i'm talking about(brake lines are attached still in image):
Next what is the 2nd line that goes up to the front of the car? Is this from the evap cannister? If so where does it go to and will i need it? I plan on having the car emissions legal.
Thanks,
Steve
