I’m preparing to service the fuel injectors on my 1992 4.0 litre. The manual shows this diagram of the fuel injector spray pattern with the caution to correctly orientate the injector.
I then find that the injector to number one cylinder has been cable tied at 90 degrees to that, and that I have been driving this way for ten years, since corrected.
The GREEN BAND injectors on the US MY 1993/94 are the ones that need orientation.
The ROW (rest of the world) might have MY different than the North American models.
The early engines are just regular injectors.
There is a different part number for the injectors related to the engine number but I don’t remember the split in the production dates.
