Exactamundo, Cap. Been in use for several years and works fine. I just found a piece of soft copper tubing whose OD almost matched the ID of the relief port. I think it was 5/16 air conditioner tubing. I carefully tapped it into place with a small plastic mallet and then curved the outside portion up to about the parting line of the housing. From there I use a length of fuel line to a small barbed bronze through-hull in the transom. I use no clamps and just slip the fuel line off the tubing when I raise the motor. Zero fumes in the lazarette and it looks cool too, puffing thru the transom port. The motor is wintering in my shed-I'll post a photo soon.
