I have just brought a c3 1.4hdi 8v for my wife and on the way home we filled the tank right up. When we got home there was a bad smell of diesel and it was leaking onto the drive. I took the back seat out and looked through the inspection hole at the top of the tank and it was full of diesel-I think it may be the tank seal and locking ring that needs replacing-has anyone any experience of this issue and if so where should I get the parts?

Welcome to the forum Stretchy

There is a sealing ring on the top of the tank that seals the sender unit that has probably been damaged and not replaced.

I would go to citroen main dealer for it, not worth going anywhere else in my opinion.

Look like you have done the hard part in finding the leak!

Please do post back your results, a few photos always look pretty.
