Diesel leak from pipe (photo)

Howdy,

First post here, I just picked up an 08 model extra cab KUN26R with 120,000km...
Took it for a drive down to the oldies place, and we spotted a leak, initially thought brake fluid but its greasy and pretty sure its diesel.
Anyway it seems to be originating from the metal cap part on the pipe circled in the picture, theres not heaps there, but it is definitely leaking.
Hose says "RT 08 FUEL 01" on it. The picture shows the fuel filter to the left bottom so you can have an idea where it is.
Any ideas for a fix?
Cheers,
Rob

they are breather tubes. no diesel / fuel in those.

maybe from somewere else. did you put some on ur finger and have a sniff?

Yeap closer look seems like diff fluid... Ive separated the 2 lines (big and small one) to see which one is leaking... There was a noticeable amount in the passenger wheel area... Now suspecting the smaller pipe which goes to the ADD unit under the engine...
Cheers,
