16 valve fuel lines and injectors

any ideas wheres the best place to get 16valve fuel lines from (all from metering head to injectors and warm up), or would it be cheaper to get some made up,
also had a quick scout round and am i right to say that the 8 valve injectors are diff to the 16 valve?
in the process of getting stuff ready to fit 16 valve, just doing some research and sourcing parts,
thanks
