Holley 1850 fuel transfer tube seals??

It is yes, so do you install the seals on the tube and push in or install in the bowls first? If i put on the tube first then they bulge out and don't want to go in the holes in the bowl, if I put them in the bowls first the tube dosnt want to go in even with dishsoap as lube they seem very tight?
I put them on the tube first, LUBE them with some penetrating oil and they go right in.
