Apolagies for the silly question but ive searched every where and cant find an answer and only just about managed to get a picture of it, albeit a crappy one!
Reason is i can hear is hissing when my engine is idling and when i wiggle it around it gets worse. The pipe connects to a little valve thing that tees off too the inlet manifold and somewhere else. Its the black pipe to the right to where the fuel pump goes, cheers
