Fuel lines

I've been wanting to redo my fuel lines on my 2006 LBZ CCSB with braided stainless steel. Anyone done this? I've seen some connectors that I can use to make all the necessary connections but was wondering if anyone had tips or suggestions.

Possibly going to be adding a fass or airdog when I do this too.

Just trying to keep from spending over 300 bucks to replace my rusted out lines. I've got a couple of patches in them and I need to do something soon. I figured using the braided stainless lines would last a lot longer too.

How would they compare to just bulk fuel line for longevity against the North salt?

I don't know exactly how they would compare. Just figure the stainless braid would help protect the line a little better.

So, whatever route I decide to go, what size lines do I need to re do the whole setup? I plan on buying extra because I will plumb the lift pump in with all the same line.

I think most of it is 3/8" and the lift pump uses 1/2" but dont quote me on that.

I replaced my fuel lines with stainless steel lines from classic tube. Cost was approximately $300 plus the cost of a new fuel cooler as mine started to leak after putting the new lines on

Did you just buy bulk rolls?
