Refitting injectors
Discussion
Had injectors cleaned by injectortune but having trouble getting them back in. I used engine oil on the new seal but it seems a very tight fit. Can't get them other than a short way in. There is copper coloured ring about 240 degrees around in the injector aperture as seen below:
Obviously I don't want to hit it (the injector that is!) and I've tried a long socket over the injector end and pushed hard but it will only go a very short way in. All the apertures are like this. Do they just sit in there almost loose until fuel pressure comes up? Is there a technique I'm unaware of?

All 8 are like that, it's not dirt. Injectortune changed all the O-rings but sent all the old ones back as well, they look the same.
Found a thread on the Griffith forum where a fella put them in the fuel rail first, using the tightening down of the fuel rail with its 4 nuts to ensure they are pushed home. Seems a good plan:

To get mine off, I disconnected the throttle cable at the lever end & the stepper motor connection so that I could swivel the plenum through 90 degrees. It was then possible to tilt it enough to clear the rearmost trumpet without too much trouble.
I also found this after much searching. OK, it's for a post 1999 Range Rover but it suggests fitting the injectors to the rail first:

Fitting the injectors to the rail first made it fairly simple.
They only really 'sit' in the inlet manifold with the nuts securing the fuel rail sufficient for me to have no leaks. Immediate improvement in idling from cold. Doesn't seem to be running on only 6 or 7 for the first couple of minutes now.
Getting the plenum back on WAS fiddly, especially trying not to make a mess of the RTV sealant bead I'd just put on.
