Ok here's what I found out ,
The Advanced part # 64492.1 , is the right size = 10mm X 14mm X 2mm
It is NOT for use with fuel however, not too much else I could find out about it though.
The John Deere part # R26286 is the right size and is made of Nitril so it's fuel safe, this is the one I put in and my leak is fixed .
Thanks for the part #'s , mine came out in brittle pieces so matching it up wasn't really an option.
