I did some checking around , some one also gave me a number for Advanced Auto O-ring ,
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, this is the one I put in and my leak is fixed .
Glad I did have some part #'s to reference , mine came out in brittle little pieces I had to dig out of the ring , not much to match up after that.
I greased the O-ring and the male connector and seated it a few times , definitely a tighter fit now.
