Question Fuel Priming


I've got a 300d with the white plastic primer handle. When I pump I get lots of fuel seems to come up the outside of the inner pump tube. Doesn't seem right! Does it?

What year is it? I believe hand pump become obsolete in 1986?
The fuel never suppose to leak outside, unless you open bleeding screw. If I recall the older engines had bleeding screw on the top of fuel filter.
