C220 cdi S203 Fuel leak after MOT and filling up

[merc07]

The day after my MOT, (maybe just a coincidence) I filled up with diesel and noticed the under side of the rear of the car covered in diesel.

I cleaned it all off and kept an eye on it but it is still wet under there a month later....seems to happen when I fill up. I'm not filling it to the brim either now, just 3/4

Any ideas ???

Cheers

Happened with mine, turned out the seal on the top of the tank (sender unit?) wasn't there, could just need a new seal.

Well the sender unit was loose - not even hand tight. Don't know how, no one has been near it

Even though their garage was full my local indy looked at it straight away as I waited. I'll see how it goes, may be ok now if not I'll get a new seal fitted,
