Re: Polar Bear Suburban

Larry, I had a question about what you used for the fuel lines in this truck with the 8.1L. If I remember correctly, I read somewhere else that you used the factory TBI lines up to the fuel filter, and then ran something else to connect up to the 8.1L fuel rail. Do you have a parts list or description of how you tied in the 8.1L fuel rail with the TBI lines in your suburban?

I'm getting the parts together to swap in an '04 C5500 8.1L into my '86 454 C20 Suburban. I'm planning to snag the fuel tank pickup and lines from a TBI squarebody suburban, and need to figure out a clean way to hook them up to the pressure and return ports on the 8.1L. I'd love to know how you did yours.
