fueld system 310
On my 310 the fuel shutoff is accessible via a little lift up access panel in the cockpit port locker. You can get to the shutoff as well as the pickup tube if ever necessary. The filter is definitely a replacement item. Read all the posts about bleeding the system, etc. before proceding, especially if you've never messed with a diesel, unlike a gas engine,air in the line will not work its own way out.Don't forget there is another fuel filter on the engine itself. Read the posts about that one too on this site.have fun.
