apparently the pump was not strong enough (pressure) to load on the first crank. When the vehicle was cranked the second time the lines had fuel and the second crank would finish loading up. I t died a slow death. I've been used to fuel pumps just dying miles away from anywhere.
The installation of the fuel pump is no joke. The tech wrestled with it for hrs twice. There was an O-ring somewhere that needed replacing, supposedly this was the "running out of gas with fuel left" syndrome that the car was exhibiting.
I changed the FPR, the switch and I have a CPS that I will replace since it's here.

anyone experience this besides Coloradogrant?
I thought the tech had it this time. The car drives awesome until it consumes 8 gallons then it runs out of gas or the pump doesn't pick up the remaining fuel in the tank.

Still have a hunch that you've got an air leak around one of the O-Rings or pump gaskets that serve the re-circulation function between the two sections of the tank. The eBahn notes make clear that any leaks there are a bad deal...

I'm trying to remember if the volume of the two tank lobes is spec'd somewhere. If one tank section is roughly 8 gallons-- it's probably a clue.

it seems that the smaller side would be a good candidate for 8gal cap. Looking at the diagram makes me wonder if something is amiss with the adapter plate (1).

So it would appear two of the three suction jet pumps (2, 3, &amp; 5) aren't working. This would seem to cause strain on the fuel pump I would imagine. Maybe this is why it took two tries to start?

A few notes from the manual:

Preliminary stage of electrical Fuel Pump (FP) generates a suction jet (thicker arrow) that is pressed into the 3 suction jet pumps - 2 - , - 3 - , and - 5 - via a nozzle and is thus accelerated. This acceleration causes the surrounding fuel in the individual chambers to be carried away and to be pumped via a line to adapter plate - 1 - of baffle housing.
The main stage of electrical Fuel Pump (FP) pumps fuel from baffle housing to engine.
Preliminary stage of electrical Fuel Pump (FP), suction jet pump system, and baffle housing constitute a closed circuit in fuel tank.
<b>To guarantee a reliable engine start, baffle housing must always be filled with fuel. So that this is ensured even with a small top-up quantity, filler tube - 4 - discharges directly into adapter plate - 1 - of baffle housing. Fuel is therefore guided directly into Fuel Pump (FP).</b>
