Found Fuel leak at Tank, need help/info please

[jaima]

Hi All,
I think I might (probably) have found my "fuel leak" please see pics.
Does anyone know the part name & number?
Can it be replaced?
Is it a screw in part?
Any help or info about the part is gratefully received?

Thank you

I found out this part leads to the "fuel expansion tank" and BMW do not sell the green part only, it is supplied with the hose(s) connected to it!

Where will I find the "fuel expansion tank" and can I fit the new part without having to drop the fuel tank ???

I am led to believe that the actual green part in the pics has clips on it and to remove the part I can prise it out with a screwdriver ?

Thanks
