Ok guys, REPORT. Good and Bad news.
GOOD NEWS: Swapped the two lines around as mentioned and it did indeed help! I did have to crank 2 times, 1st around 30-40 seconds with stumbling (music to my ears at the time). My battery was getting weak, even though I had it jumped to my Neon w/ heavy 4 gauge at least jumper cable. I stopped cranking and charged up off the Neon as she sounded like she was wanting to come to life. Touched the starter and she wasn't too hot yet (warm :-) , so I proceeded a second round. After about 30 seconds she roared to life. Revved her up slightly to help clear out some air then let her idle. She idles nice and I don't feel the slight stumbling in the steering wheel like before.
BAD NEWS: I proceeded to the engine area while she was running. I examined the fuel lines while she was running at idle and didn't see any air bubbles. I revved her up manually and low and behold, I see the same air bubbles as I did before, but the engine did not visibly stumble as before the o-ring replacement.
NOTE: When I swapped the lower fuel lines as addressed earlier in this thread, the line going into the upper opening on the lift pump is not very snug. I don't see any fuel coming out (yet) but feel this is where the air maybe still be coming in through. The lower opening on the lift pump has the fuel line snug onto it. By snug meaning I can grab the fuel line on the threaded area after the joint, wiggle the line and the line won't move. Not the case with the upper line.... I will include the fuel line diagram from the prior post, and the affected line that I stated feels loose (non-snug) is 83. I have also included photos of how the lines currently appear. From this diagram lines 83, 74 and 56 visibly have air bubbles.

- My marked photo to which lines visibly have air bubbles circulating through under throttle [Image 5]
NOTES for STARTING: Prior to commencing any starting activities I always jump my car to another vehicle (donor) to conserve and assist the E300's battery during starting duties. Once connected and the donor car running I commence with the glow plug sequence and wait at least 15 seconds to help the battery slightly recharge from the glow plug system drain on the system and letting the glow plugs heat up nicely. After the 15 or so seconds I proceed with the cranking of the engine continuously for approx. 30-45 seconds. I won't crank longer than 45 seconds for fear of overheating the starter. The key is to maintain sufficient power flow to allow the engine to keep cranking. Hope this helps someone :-)
