    Heres what my list looked like.
    #'s 1 & 2 look good on your list, my truck was an 87 so I already had them.
    #3- AC Delco EP381
    #4- 3/8 compression to -6an (SU feed)
    #5- 5/16 compression to -6an (SU return)
    #6- 20' of 3/8 (-6) stainless fuel line
    #7- 3/8 gm quick disconnect to -6an fitting (ls fuel rail supply)
    #8- 5/16 gm quick disconnect to -6an fitting (ls fuel rail return)
    #9- 6, -6an straight fittings
    #10 inline high pressure fuel filter

    You want an AC Delco EP381 for a fuel pump, not the walboro you have listed. These can be had for $25 or so. Is what I used and WILL mount up to your sending unit like factory.
    Better off in the long run to convert to AN fuel lines.
