I'm completing my engine build and I have a 2001 2.4L LD9 engine and I planned on running 750CC injectors. I got a set of RC-SL4-750 Injectors and they do not fit in my fuel rail and don't fit correctly into the head of my engine. Anyone know what went wrong here. I used the same part numbers I saw on Carcustoms.net but they didn't offer 750 cc injectors. Anyone with information on this i'd greatly appreciate it.
