While removing the old carpet from the Stern shelf above the engine room, I noticed my fuel vent fitting broke off the back of the hull inside the boat and I'm not sure what to order. Mine is about 1/2 inch wide or 30mm. It's a llittle short of a dime coin in width. I'm bad with fractions. Could it be a 1/2 inch? I noticed they don't list width of vent fittings in mm.

should be 5/8" vent fitting (16mm)

measure your hose. you most likely will need to either plumb in the P-trap or make sure your new vent has the p-trap.

Mine doesn't have a P trap it's a straight fitting. I just remeasured it, it's 16 mm wide, your correct.
