Chances are by the time you've paid extortionate P&P from Deutschland and more to HMRC it's cheaper to get them from the dealer anyway.

To this day I say that if I could buy my old 740 SE new out of the factory I would. Good luck

If you have fuel pressure and airflow through the fuel distributor, you should have constant flow through all the injectors. With that in mind, how were they testing things?

Here's the message: "Yes no problem, the technician stripped the injectors out and there is constant flow of fuel through injector 1 and the remaining 3 injectors are showing signs of being weak. Injector one is the worst by far but we would only recommend replacing all of them due to weakness. We would then need to reassess once this problem was rectified." |

I still want to replace the O rings though, you can see what I think is the first one around the plastic case in the photos but isn’t there a second one? |

You have to get the plastic case off the injector to reveal the other "O" ring on the injector body. See the thread i linked to further up about it. Use silicone grease to help the new "O" rings on and so they don't snag as they're fitted - makes life much easier.

I managed to get them off in the end I just took off the plastic covers first. The plastic cover for injector 4 actually came off with the big O ring attached to the inside and the one that goes on the outside of the plastic cover is sort of molded to the cover as you can see in the photos.
