It turns out NAPA says the pump is not available, either at its warehouse or through the mfg. So, I ordered the Airtex 3450.

OK. The Airtex 3450 is looking pretty good about now.
I notice that one of the ports is shown to be at about the 11 O'clock position. My outlet port is there. This is where the steel hose connects. I can't tell where the second port is on the AT 3450. But my inlet hose is rubber, so if needed I could easily reposition or replace it. Here is the link to the picture: http://www.summitracing.com/parts/ATX-3450/?rtype=10 Can you tell from it that the port shown is, in fact, the outlet? I am merely wanting to avoid having to re-do metal hosing. You can see my existing get-up 2 pages back where I submitted a photo of it. Thanks for all your patience and assistance. I am just trying to insure an easy job so I can be done with it. I don't know what a re-build costs, but for $60, new is fine with me.

I used a rather "earthly" attempt previously. I disconnected the hose at the bowl and cranked the car quite a bit, while watching the hose from beneath the hood while I cranked. I could see from the driver's seat while cranking. Nothing.
So, maybe it is a volume issue. Do you guys agree that the only two things remaining are the hose to the bowl and the pump, itself? As far as the eccentric, the picture I took is probably the best look I'll ever get of it, so I don't know that comparing to anything will help. I need a new signature: "Learning how cars run, one component at a time."

Yeah, I'm not ruling out the pump. By looks of things, eccentric is fine. I will check the hose from outlet to bowl. If that's okay. I need to check bowl. Not sure of what I'd check for in the bowl exactly, but I'll cross that bridge later. If bowl okay, then must be pump. I rule out anything from the bowl to the carb because of Howard's advice that the bowl should be full.

Eccentric: (Does it look good to you? Seems fine to me.)

As to the above, I am wondering what it's normal level is. I have tried a lot to start the car, and so I wonder if the bowl should be dry. Or is it that the 2 tbsp is a low level that prevents circulation to the carb?

Thanks.
I just took the pump back off, and did some checking. I am suspecting there is some issue besides the pump. This time, I connected the gas inlet to the pump and manually cranked it. It pumps gas. So either the eccentric is not working the lever, or I have some kind of blockage. Tips of things to check would be appreciated. Here is the way it went down. I drove on a hot day, and the car got pretty hot. It was all freeway driving until I exited the freeway. On exiting, I made it through the first stop light. At the second stop light, it went out. I noticed coolant overflowed. Had the car towed. Checked a few hours later and noticed the pin came out of the fuel pump. I removed the pump and put the pin back in. I made some errors trying to put it back properly - namely, failing to put the rocker arm in the slot inside the pump that raises the diaphragm. I corrected that, and re-installed. No luck. But if I dump a little gas directly in the carburator, the car will start for about a second or 2. There is no damage whatsoever to the rocker arm of the pump. I would think my options are limited to: 1. The eccentric. 2. A clog between the fuel pump outlet and the carb bowl. 3. The bowl. Incidentally, the bowl has a little gas at the bottom. It's not full, but it does have some gas. Maybe a couple of table spoons worth. #2 will be easy to check. I can take the other end off at the bowl and blow into it. Not sure of what else I should be looking for. P.S. When I manually cranked the arm, gas came out as I said. It was not like a hose, but it was enough to clearly show that gas is flowing through the pump. Sometimes, it would spurt a little like a tiny fountain. It did a bit more than just dribble out. But again, it was not a super-heavy flow. By the looks of it, I would think that the flow was sufficient when you have that going on constantly and with a fast cycle.

Not economics. Bruised knuckles.
I just want to get back running the easiest way I can. If the exact same pump I have was available, that would be my choice. I am not familiar with rebuilding. I wouldn't mind sending what I have to be rebuilt. I just don't know who to send it to for that. (Ficken did well on my wiper motor).

I'd really like to find one with the ports in the exact location of mine, especially as to the port to the carb, since I have a metal hose on that one. See pic:
