Because cast iron's coefficient of thermal expansion is only about 
1/3 that of aluminum, cast iron pumps are always leaky once the 
engine warms up. While expensive cast iron pumps HAVE been made for 
the air cooled VW, I don't think anyone has ever made one that you'd 
want to use. Get a good alum one.
