hello i just purchased a 1988 yamaha excel on a 24' boston whaler the previos owner disconected the oil pump lines and ran premix i am going to install a new oil pump on the boat and put it back to the oil injection as the pump sends out pulses of oil to each line do the lines have to go on the pump in any certain order to each cylinder it would seem to me that it wouldnt matter but i wanted to check before causing any damage any advise would be appreciated thanks.
