I noticed that my fuel tank leaks on a strange spot...as you can see in the pictures.

Anyone had similar problems?

Is it possible to repair it or is it wiser to buy a second hand one?

what car is that?

its either a clio or megane, but which and what model?

If clio 16V then the pipe ontop has probably popped off as no clips are used to hold it on!

It's a R5 GTE.

That "thing" I've circeled has no connection on any fuel lines as far as I saw few minutes ago when I jacked the car up.

The small tank connection to main tank seems fine, the pipe that leads from filling cap to small tank seems ok...

I don't know what's the use of that "bump" I've circeled on the sidewall of the reservoir...

But that's where the leak comes from.

bump looks like the pipe outlet to the aux tank on a gtt but the tanks to far over to 1 side, its not sittign right.

drop it and have a look, I always find the leak to be from above.

it's leaking from this inlet looking thing, but that part needs to be blocked...

plastic could be welded - cold welding, or liquid metal (that's how we say it here, i really don't know the term for that in uk)

clean it up first and have a look.

Cold welding is plastic welding here but its still hot enough to light a fuel tank up.

You need an epoxy of some sort.

here we just wouldn't fill the tank anyway more Laughing
