Quick follow-up: there is this black box right below the pull rope which I presume is a silencer. Upon examination, there is a little hole toward the left hand corner. Could this be where you insert the tube and spray?

Edit to add: the black box I speak of is part #36 in this diagram http://www.crowleymarine.com/j...6.cfm

Thanks,
Jake
