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).

They are relatively easy to work with. Order some anodized vice jaws and the anodized wrenches. I used 6AN for all of my fuel and transmission lines in my LS swap.

A few other tips: Use a pick to strip back the stainless mesh, your fingers will thank you. Use assembly lube on the fitting where the hose slides on. Use antiseize on the threads. Take your time. I wrapped the PTFE tightly with electric tape and cut it with a band saw.

Different brand and a few extra pieces (which is great cuz I bought them all separate) but this is what I used for both transmission lines and fuel lines. Easy to work with and great looks

That looks pretty snazzy.
