502 MPI - valve cover vent tube size.
One of the 502 MPIs in my 311 is missing the vent tube that goes from the flame arrestor to the valve cover. The mechanics (if you can call them that... a comedy of errors on this one) lost the tube. I'm going to replace it with some fuel hose, but I need to know the sizes (I'm thinking 3/8 at the arrestor) particularly the diameter of the breather grommet on the valve cover. I'm. It at the boat, and will be picking up some parts this afternoon. A search hasn't come up with anything.
Thanks!
