I am currently away from my vehicle and was wondering if a 2005 2500 Suburban with the 6.0l non flex fuel has two fuel lines that come up to the fuel rails (input and return), or just one with fuel pressure regulator in tank?

its possible im wrong but i believe 04+ on gm trucks is returnless

Ok thanks! By the way your truck must be one hell of a beast. I assume that 8.1 spools that 76 really nice!

1-2 = 0 boost but 3rd gets nasty.. gonna swap to twins under the hood asap.. 50-100+ is fun.. played with a corvette and he wasnt happy
