Diesel leak from the top of the tank....

[Mult-problems]

Hi guys + girls,

I'm a new Berlingo owner and managed to buy a 2000 Citreon Berlingo - WAV conversion with 1 previous owner and 22,000 genuine miles.

The van is great and hear they are quite the workhorse.

However,

I've discovered a diesel leak. It seems to be coming from the top of the tank and it has diesel all along the bottom of the van and is dripping from several locations. 

Does anybody have any knowledge of this happening in the berlingo? Or what should be check, whether to remove the whole tank etc?

The fuel tanks which I think are plastic . Its possible that the conversion has caused something to rub a hole in the top of the tank?
It looks a lot of leak for a small hole in the tank

Could it be the fuel return line dislodged or chaffed through.
If it leaks with the engine ticking over, I would look for the return fuel line and see if its OK.
If not then tank out I'd think.

I will give that a try today, I'm going to jet wash the diesel off bottom first.

I forgot to mention it cut out when the missus was driving it. Jump started and it was chugging and struggling to stay on.... accelerator cut it back out again.

Ran with fuel filler cap open and ran just fine after 30min.

Never had this with any car!

there was a post by 357356 yesterday about the air vent for the fuel tank , check that out . It may help in the cutting out bit , maybe has a bearing on your fuel leak.

Coincidentally I have just dropped my tank (2000 Berlingo 1.9D Multispace) to replace sender. I have no sender access though many Berlingos do have!
The fuel lines are recessed below the level of the top of the tank. IMO if the top of the tank was rubbing and holed then you would not get this amount of leaking. It sounds like one of the fuel lines is fully attached to the sender and fuel is escaping.
