The efi pro kit has the full wiring setup you need and the correct tank selector valve so it returns to correct tank aswell everything you need in a kit
If you already have pumps you can buy the harness and valve separately

They have a couple nice options for dual tank efi I recommend the dual pump option but single setup works too
I like ptfe an style fuel lines but rubber an lines work too but the ethanol in our fuel will eat them eventually
I really like rough country products. Never been disappointed with anything from them. I would recommend getting the upgraded v2 shocks. The base n3 shocks are way to stiff.
That said skyjacker makes a good kit too(get the kit with all 4 springs and the black max shocks)
