Finally got the feed line changed out, the feed line is part #24576680 and the two o-rings are #12339317.
Also if you haven't already, you should probably check the condition of your Map sensor hose, it caused a misfire and I found the hose just sitting there rotted off on both sides.
A new one is part # gm6148-m
After doing some math, I found it's got 71K miles on NGK G-power single plats I put in, in 2007, still running ok, but probably time to change em out.
