TD5 fuel filter housing leak

I've had a bit of a scout around but thought I'd ask direct before I start stripping it down.

When left over night my Td5 is a bitch to start, it air in the fuel line because if left in purge for a few mins it starts ok and for the rest of the day it starts first turn.

So had a poke about and noticed droplets on the rear door and wheel cover.
Traced that to the fuel filter housing, cleaned it all off with carb cleaner and left of a couple of days to observe, it appears to be coming from the top of the housing from the area of the forward facing outlets so I suspect filter housing/connectors/pipe.
Anyone else had this?
Cheers

They do leak from time to time. May just be an o-ring gone or something come loose.

Remember you are having 4 bar of pressure in the system, so it really needs to be sorted out.

I would 99% say that you have a chaffed fuel line, very common on the TD5 Discovery.

It,ll be chaffed through on one of the bends directly from the filter where a poorly routed cable has been laying on the fuel line.
