I had a petrol smell coming into the cabin when starting and @ low speeds, I found that one of the fuel hoses was leaking where it left a round metal thing in the line. So I slapped a jubille clip round it and vola bye bye fuel smell, this am I smelt it again and have been for a drive it seems to be using alot of fuel.
I found its now the pipe between the other side of this mystery round thing and the engine. Question is what is this thing, im worried it may be blocked.
P.S. Its a 1.4i Multipoint engine
