Aah, I get it! I had a vision of turning on the shop vac and having the screen attached to the hose. Something about the procedure just didn't add up!

Perhaps I was lucky when my SD wouldn't run. I dumped some Startron in, let it sit for a few days. When I did turn the key, problem solved. It only required a close guestimate based on fuel volume - no agitating the fuel or pulling the strainer. Try it as a 1st step. You can always clean the strainer or pull the tank later.

That's a very bad idea, unless you want to risk getting burned or blown up. With diesel the chances are much less than say gasoline, but essentially you're sucking up fuel vapor which can be ignited with a spark (not so much diesel, but still).

Got the car running yesterday.

I went and switched the return and supply lines. Subsequently started pushing on the primer to remove any air bubbles and noticed that the primary filter looked odd and would not allow fuel through the filter. I pulled it and put in a new one after examining the old one. The old one, maybe a couple of weeks, had the mesh completely covered in black goop. So much for my previous check of the primary filter.

Bled the lines through cranking for a few minutes, idle a bit rough at first and then smoothed out. Went back and checked the new primary filter after a 10 minute drive through the neighborhood and the new filter was very gunked up again but this time with what looked like mucous. Tan in color and very similar to the look of Chinese hot and sour soup. Changed the filter again, 10 minutes later same thing.

Then swapped the fuel llines back to original config and the primary filter stayed clear. I need to check it out later today and see how the filter is holding up.

I guess the culprits are black goop (fungus), plugged primary and my fault of missing the plugged primary the first time Lesson learned...check the simple stuff once and then check another time just to be sure!!

I also added another ounce or two of the startron for additional insurance.

Reagarding the return fuel line.....how far down into the fuel tank does the return line go. Does it dump in from the top or does it go to the bottom of the tank. The reason I ask is because I am trying to determine where in the tank the return line was pulling the "hot and sour" type gunk

Still have hot and sour soup in my primary filter. I felt some sluggish this morning and even had to pull over to the side of the road and rev it up a bit and get going again. I made it to work but will probably change the filter before I leave work this afternoon.

You could do with fitting a water trap,it will collect most of the muck which can be disposed off.

The one in the link is something along the lines of what to go for as you can see what has been collected.

You could just use a normal filter unit that has a trap and a drain built in as standard and place that before the primary filter.

If one could run without a filter unit inside it,and I am not sure if it needs to have one to make a good seal then you could just drain it after covering a certain mileage
