Then I added removed the diesel from the tank and added my 50/50 mix to the tank and drove until it got hot and then stalled and would not start.
I did run it from the bottle through the primary filter the same as it comes from the tank. It seems to me that the tank or the bottle the fuel pump is still pumping from fuel that is not under pressure. Since it works so well on the 50/50 mix from the tank I'm assuming that the lines are not clogged. I know the line from the bottle is clean. It should be the same flow from the bottle or the tank. Right?
I'll try this after the primary filter from both sources and see what I get.
The return line was not submerged in the bottle so I could see the fuel being returned. When using the hand pump you can hear the relief valve opening and see the fuel going into the bottle. Since I don't have anyone to help me here I could never see the engine running and returning fuel because it wouldn't run long enough for me to get out of the car to see.
Sounds like a real challenge you are about to get into. It may even be the same problem I have with the IP getting hot and failing.
It must be rather chilly up there in Nova Scotia. I've got some family roots up that way.

Sounds like you are applying some thought. Your engine will run with the non turbo pump if required . Just no fuel enrichment on demand. Again depending on where you live a good cheap turbo unit may be at an auto wreckers. Or from an old car sitting somewhere.
. Taking the time to actually meter the pressure is not only a good ideal it tends to make guys like me a better troubleshooter. What is occuring is your understanding of how everything relates is clarifying or solidifying.
Remember you need one of those fluid dampened gauges. Zero to thirty pounds range is ideal. Companies like harbour freight sell them for around 10.00. Since you might be experimenting with fuels I would sway towards making the gauge a permanent installation. I am not or have not been a working mechanic.
In my area the supply once reasonable of 123s has dried up pretty well. Weatherwise it has been an unusually light winter overall this year. I just finished laying a few thousand bricks about three weeks ago.
Was not cold enough that I had to even protect the job from frost. Average day time temperature now is around freezing most days or slightly less. Winters locally seem to have been steadily declining in severity. Seems much colder and snowier along the north eastern eastern United States for at least the last ten years. The summers are not as warm here as they were though. It's the old story. You cannot win.
