Fuel hose sizes?

My 1.4 340 is currently pissing fuel left right and centre and I'd like to increase my fuel economy!

Unfortunately I went nosing about having just filled up my tank and am currently trying to use it up (strange the only time the car seems economical is when you want an empty tank!) I've already replaced all the 6mm ID hoses on the fuel pump, I've since realised that the filler breather hose is wet and I'd like to replace them all when I next get the chance. Does anybody know of hand what other ID fuel hose is used on it? And does anybody know where to get a filler neck hose/one that fits?

Cheers
Alex

I wouldn't worry about the filler, I've not seen a problem with them

However yes, the larger diameter breather hose is...umm, I think 12mm ID. Don't quote me though.
There is a network of 6mm ID hose going round the expansion tank on 1.4s and 1.7s. behind the trim on the RHS.

That goes to an unequal y piece, so two are needed. 75cm length will do the job. (you can quote me on that)

My 340 used to leak petrol very badly from the filler/breather area if I filled it to the top. One of the small pipes had perished and the metal clip rusted away. Fixed it with new pipe and clips this year when I put the car back on the road and it's been fine since.
