May be old news, but I recently learned that Zippo will replace the standard insert with a pipe insert for free, and ship the original insert back along with your lighter.
I went to the web site http://www.zippo.com/customercare/repairs.aspx and filled out the form and mailed my lighter with a request for the pipe insert. About three weeks later, I got my lighter back with the new insert, the original insert, a wallet card with Zippo manufacture dates, and two extra flints.
