I want to remove my diesel injectors to check them over. Are there any special procedures/precautions? Also, what is the purpose of the tubes leading from one injector to the next? Thanks.

When you remove the fuel lines from the top of the injector, use the finger of a rubber glove (or cling film) and an elastic band to stop dirt entering the injector body.

Try not to bang, or let anything dirty touch the end of the nozzle.

If you remove the nozzle, do not overtighten it when refitting.

Always ensure the injector seat is clean.

Always use new copper seals/washers.

The tubes joining the injectors are return lines for uninjected fuel.
