Fuel Line Question

[AU Doc]

I'm probably a year away from an LS swap, but I believe I need to replace my fuel line (I have a hard time starting the car if it sits for a few days). Having not spent much time researching this since my LS swap is still a ways out, is there anything I need to know about the fuel lines that I should do now, or can I just use a stock replacement line? That is, will I need to go with a larger line or some other configuration that I should go ahead and do now? I'd rather just replace them once :)

Just depends on your HP goals or if your going to run power adders. Also depends on if you going to run a dead head style system with a vette filter/regulator or a full length return. Usually for N/A setups a good 3/8 (-6) line should feed quite a bit.
