proper way to change both filters is: replace the clear primary, then start the car, and build up smooth idle.
then shut down the car, and remove the secondary filter, with the new filter already filled with fuel, and ready to install.
install it with new o-rings on the center bolt, and crank the car, with the accelerator 1/2 pressed down to cover the stumble as air is ingested, and let up once the stumble is gone.

Thank you so very much for all this help!
The mechanic pumped the primer for much longer than I did and eventually started. He said it takes more pumping than just no bubbles in the line. However, I like your method!
First, there was no O-rings anywhere. The filter was last changed by a long time Mercedes mechanic, so has me puzzled. Do you have a picture or diagram? How come things have been fine for over a year? I mean, how did I get along without them?
I changed the primary first, then saw how dirty the pre filter was. Mistake number one.
Second mistake was not holding the accelerator when it was just about to die.
Third mistake was low blood sugar. I did eat a snack once home and thus why posting now, but already feel hungry and not lunch time...
Glad you all are here to help me through all these lessons!
