Or?
could we cheat and back off the fuel screw some and get the collar to come over the hole and close it as it should? Just thinking out loud here.

How could that little ball in the picture above have gotten bent? Its pretty sturdy and I don't see how it could have bended in any way. I am getting fuel flow through the return line with the standard two nipple banjo bolt on and lines hooked up. I clamped the smaller line that comes from the injector lines. The pump does fill with fuel up to the cutoff solenoid but there is no pressure or not enough pressure to push the spring on the pressure valves.

If tightening down the HP head was enough to snap the link, it would be enough to bend the stem of the nubbin or the lever.

The collar only moves about a millimeter... the piston stroke is not much more than 2mm.

The collar only has to be moved a fraction of an inch to make it spill the contents of the delivery tube back into the pump itself. So Tyler has the solution to pop the top and look down in there on an angle with a bright light and see how far the collar is moving and if you can see the set up.
Given that you do have fuel coming in and going out the next part of the equation is the high pressure side of the pump. That is the solenoid and spill collar and maybe the check valves in the head. Cranking it over and applying a bit of pressure on those delivery valves with a very thin jewelers screw driver or thin rod might get fuel to come out. I doubt there is an airlock in there big enough to prevent fuel from coming out but that has been known to happen.
Man this has to have you tearing your hair out.

So the thought on the bent nubbly was an excellent one. We took off the top and tried to move it and the collar its self was really tight on the shaft, we suspect because it wasn't put on perfectly straight on the shaft. A couple of taps with a screw driver and ball peen the collar floats freely with the assistance of the nubbly. We will proceed to put the cover on again and try to crank it. After initial adjustments we proceeded to rotate the engine by hand while pushing the lever in and letting it spring back several times throughout rotation. Cross your fingers.

Well no such luck. Still sucks fuel in but nothing out. Trying to get the factory clamped collar off of the fuel governing screw so we can screw it in that way.

I also screed the governed screw in as far as I could (threads were screwed up where the factory collar was welded on and no avail.

http://www.ebay.com/itm/140741285359?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649 the pump in question. after doing some reading i have concluded that this will most likely work in my car since the aneroid is only used for altitude compensation. Anyone want to buy my pump? All new seals...huh huh? The only thing that concerns me about this pump on ebay is this statement..."NOS means new old stock. These are items that are still in new and unused condition that have been on the shelf or in storage for a number of years." perhaps the seals could be worn?

As I lay here in my bed, thoughts going through my head, it has occurred to me that I never took note of how the vertical shaft that goes to the governor spring is oriented with the spring throttle control mechanism. Perhaps the vertical post is not "twisted" far enough to pull the lever far enough to slide the collar far enough to open the hole. Do any of you guys gave pictures of how the line at the top of the post is supposed to be oriented with the lines on the throttle lever? Which direction should that vertical post twist when looking down on the pump from the top? Is the horizontal part of the governor supposed to be closer to the alternator side of the pump or the engine side?

And what is the proper procedure for keeping the vertical part tentioned or twisted while hooking it up to the lever inside the pump and threading the nut for the throttle?
