Fuel Injector replacement

[owenisrael10]

I recently needed to replace my left side fuel injector. I was told by a few mechanics i would have to get new hoses that connect to the fuel injectors from the high pressure fuel pump. I have been searching for it as a 'fuel rail' with no success. Engine model is the n63TU (N63B44O1). Any help appreciated!

Not sure why you’d need to replace the fuel rail. What year is your X5 50i?

For bank 2 it’s 13538649321
For bank 1 it’s 13538649320

Not the rail, the rail to injector pipes. The ends are soft to be crush deformable for best sealing. When removed the first impression made from prior install may not coincide on subsequent re-install and leak. Often they don't, but better safe than sorry rules say to replace for every common rail diesel or gasoline engine for which I have read manufacturer's procedure.

The rail and rail to injector pipes are all one piece on each bank for the N63/S63
