the way i've always seen it done (at independent porsche mechanics) is
with a larger needle-nozzle and sticking the needle between the axles
and the small end of the rubber boot, by sticking a small
phillips-head screwdriver in first to create a little room. they
removed the clamp on that end first, of course. :)
