I am in the process of buying the proper fuel line to connect to my fuel rail, but I have some doubts. I have a 1998 Z28 LS1 and the fuel rail connections are a bit confusing. I can see it had two lines connected, but I see on other threads that only one is being used. There is a part connected to the fuel rail that I am not sure I need and I am wondering if I should remove the extra hoses after the fuel rail hard line connection. Those hoses come with a port to check for fuel pressure, do I need that? How exactly should I be connecting to the fuel rail? Just like to make sure that one of those fuel line kits will fit my application. I am posting some pictures to see if I can explain better my questions. Hope you guys can help me, want to make sure before I spend $350+ on a fuel kit I am planning to order. Appreciate the responses in advance.
