Leak after replacing diesel filter

[Evyater g]

Have a leak after replacing the diesel filter from the down hose

[geoff]

Some filters have " screws " on the top of them - bleed / drain screws I believe - maybe one on these is slack ? maybe one of your push on fittings isn't seated fully ?

Presume it is a 1.6 Hdi from the photo ?

A 1.6 filter can be lifted out of its housing to gain access to " looking " at the pipe connections even with the pipes still connected, maybe you could lift the filter and take a look ?

Unlikely that the filter itself has a leak through the body as it is a moulded item.
