Jim this is the way I do it, I just pump about two pump strokes into the vent, that usually causes a little to exit the front bearing. It has never effected to front seals ability to do it's job. The larger than .62 engines require 3 pumps strokes.
PS, I ought to mention that I drilled out the original spray aperture and inserted a piece of the plastic fuel tubing that comes with fuel tanks and I never use.
