When you change the filter plese fill it with somethinf. Don't leave it dry or mt. It will be impossible to start it. Most will fill it with atf fluid and diesel. Some use injector cleaner. Only fill the outer ring of holes in the filter. Otherwise any dirt that gets into the center hole will go directly to the injection pump and cause problems. If you have an electric lift pump instead of a manual pump its much easier to change this filter...
