I reused the old ones without any issues. I also purchased my OEM injectors from AB through Ebay.Did you guys replace the injector clips, or reuse the old ones?
If you got to the point of removing just about everything, here's my post on the easy way to remove the fuel rails on both sides. https://www.landroverworld.org/threads/diy-timing-chain.31050/#post-190524. You'll need the injector removal tool to actually remove the injectors, just make sure the tool is seated correctly before you try to slide hammer it out.
