I went to replace a fuel filter on I evinrude 70 I bought, one line going into the filter is 3/8, the line that would come out is a 3/16 that goes to the motor. My problem is I cannot find a filter or a barb mender that is 3/8 one end and 3/16 the other end. can anyone tell me how to fix this issue? I do know the 3/16 line on the motor looks to be original and not sure on the 3/8 running from the tank. I need help please!!
