AN fuel line kits

[K5Rob]

Hey guys got my LS set in my K5, I think I’d like to go with the AN fuel line kits found on ebay and the like. I will need a kit for fuel and also transmission lines.
This will be my first time working with AN fittings. Does anyone know what size line is appropriate for a mostly stock 5.3? Also any tips will be appreciated.

I have used AN fittings before. They are not my preferred setup because they are not the easiest thing to work with. They are not cheap, and you have to have all the correct parts or it won't work at all. Hoses and hose clamps are way more flexible when it comes to installation and modification. (no pun intended).
