Seperating injectors from fuel rail
having a bit of a check tidy up in the engine bay and have removed the fuel rail and stacks with the intention of getting the injectors cleaned and checked any advice on separating the injectors either end I have removed the small retaing clip on the top side do they now just pull out ?are they being held with the o rings ?

Yea, remove clips, undo bolts that hold rail to manifolds and pull 'em out. Be ready with some rags to soak up all the fuel that dumps out.
O-rings on both ends of the injector. Use a dab of automatic transmission fluid on the fresh o-rings to help them glide into place on reassembly.

If you can lever the rails somehow (screwdriver under the hold down tabs or under the rail itself) you can slowly prize them loose rather than tugging too hard and knacking something (hands/face/fuel rail).
Have a good clean of the area as I guarantee one will pop loose and p155 fuel everywhere and wash and grit or crap into the hole you just yanked it out of.
Good luck!

^^^ yep - The lower oring is quite recessed and as such a load of crap builds up on top of it. (at least mine were) Get a can of carb cleaner with the fine straw on the the end to blast the crap out before pulling them out as it will go down the hole

You can DIY, but to be honest I'll just hand them over to somebody who does it professionally rather than mess about with all the chemicals and electrodes myself. The costs I've heard bounded about doesn't really warrant DIY in the same way Powder coating isn't worth DIY either.
