I just recently built a ls1 for my z28 due to me blowing my other one up, in the process i i deleted all of the evap system and did away with my ac etc. My question is im about to purchase some fuel rails but im not sure if i can set it up with a return system for the evap fuel line or to to just run the fuel feed and block off the evap line ? what should i do and the effect it would have on the tank itself as far as it pressurizing any negative effects of which im unsure of.
