Looks like you have a 500 piece Barracuda puzzle there.
My progress was slower. Put on the 1/2 prebent stainless fuel line and the 1/2 stock-type pickup. Then the 1/4 stainless return line. Then visits to the hardware, auto parts, and marine supply store looking for a short piece of 1/2 rubber fuel line, not found anywhere. I'll use a piece of heater hose till I can find one.
My AN fittings finally showed up so I get to practice making up hoses. 14 pieces and 3 different size hoses.
