Fuel filter drain plug leak

[matthlock]

My Xsara Picasso 2.0 DCi has developed a diesel leak from the drain plug on the fuel filter housing - I think the washer was damaged the last time I tried bleeding the fuel during a filter change. The scrap yard wants £30 for a replacement but I'm reluctant to pay that ias it's just a washer! For the moment I have attempted to seal the drain hole and thread with silicon but not confident that this will do the job indefinitely. Do I need a replacement housing unit or can I just by a new washer (or washer and bolt)?

It's an 03 Xsara Picasso 2.0 diesel.

Wrap some PTFE tape round the thread, you need enough so its a fairly tight fit, probably 10 turns or more. The previous owner of my 406 stripped the thread on the sump plug, every time I change the oil I use PTFE tape and it screws up tight enough and never leaks, I have done 50,000 miles like that.

would an o ring not work if not bring the old washer to an engineering supplies see if they can match it up.

silicone will deteriorate rapidly with diesel exposure you could use polyeurethane i.e {tiger seal} but this part is supposed to come apart so as to remove water from the diesel filter housing so probably not a good idea. you just need to get the washer matched up.

All it needs is a small "O" ring.
I have had a box like this for years,its got me out of trouble on lots of jobs even in the house. If you dont want to fork out for the kit I`m sure your local garage will have one.

Pound shops sometimes have boxes of assorted 'o' rings, fibre washers etc, and may well include something suitable.
