LQ4 swap fuel system question Hello, I am putting a 2003 Chevy 6.0 LQ4 in a 1957 Cadillac. My engine has 3 steel fuel lines to it. I am assuming the regulator is in the rails, and I can run the feed and return to my pump I'm putting in the tank. What is the 3rd line that runs to the front of the intake with the schrader valve, and what do I do with it? Thanks for any help.
