2001 S60 2.4 NA fuel smell engine bay

[ashgoldS60]

2001 S60 2.4 Normally Aspirated. I have started to smell a slight fuel odor after shutdown. I could not see any wetness but wiping the outside of the fuel damper I could smell fuel. It appears the damper has an o-ring but no separate part listing. This fuel rail has no pressure sensor just a bleeder valve at one end.

So I had planned to replace all the injector o-rings when I look at the damper. Am I forced to replace the entire damper or has someone discovered a replacement o-ring for the damper.

Secondly, is the damper a two piece part that is factory crimped? I am wondering if the crimp is where the leak is and not the o-ring which means I need the entire damper anyway.
