Leak After Fuel Filter Change

I have changed the fuel filter on my ford focus 1.8 tdci mk2, i now have a leak, i have attached a photo of something i found on the ground near where i was working, is it a part i have missed? thanks

Did you fit a new filter seal at the same time?

That bit could be the old seal but not sure.

It is recommended that when changing the fuel filter to always fit a new seal too.

thanks for your help but problem sorted, when i changed the filter i realised that there was no primer so roadside recovery guy came out coz it wouldnt start, he undid the injectors to help get the fuel flowing, we got it started but he didnt do the injector back up, had a mate sort it, thanks!
