Coolant leak

[Pitsmoor Col]

I have a nasty coolant leak, it seems to be coming from somewhere under the fuel filter and vacuum reservoir. I can see some small hoses but cant find a leak. doe's any one know a possible cause ? Thank you.

What car is it.
The housing itself is a source.

Common issue on the 651. Under the fuel filter there a plastic housing that cradles the fuel filter. Not a bad DIY job if your confidence. You'll need to take out the erg and the egr vacuum. A good indy should charge an hours labour. The part number you want is A6512006000

Got this sorted now, a few fiddly bits and it took me a couple of hours. Could have done with draining the cooling system to save guessing the amount of antifreeze but could not find a drain tap. Many thanks for all replies.
