hi maybe a dumb question, but what are the two small dia. hoses that run to the airbox on a 1999 90hp 60 degree v4 Johnson
there is one at the bottom on the port side of the air box and one towards the top starboard side.
the one at the top has me interested as i found it off at the oppersite end to the air box, there is a little brass barb screwed into the "motor" between the two top carbies.
while running there seems to be a vacuum or pulse at this fitting.
would there be any operational problems if this was not connected ( its back on now)
just asking, thanks
