1kz Injector change

[fweddy]

Any particular tips on injector change in 1kz.

I've replaced my cooked engine in my 94 Surf with another and its running good but getting a bit of black out the back. I had recently done the injector tips on the old engine so I'm going to look at swapping them over to the new engine. I'll be checking for any heat damage (blueing) on the injectors after the overheating. But hoping they are still all good.

Any tips, tricks or traps for working on the injectors and swapping these over?

watch the return rail hold the injector when you undo the nut sometime it turs the whole unit and breaks the rail otherwise pretty simple
