How can you clean/unblock fuel injectors? Is there a liquid you can submerge the fuel ring into or is it a case of "prodding" out the needles with a very very thin piece of wire?
Thanks.

Use water, and suck it throgh the needles and out where fuel usually comes in with a high volume pump (kavan fuel pump e.g.). So flush it in reverse :-). You can also use fuel if you wish....it is just important not to flush it in the direction of fuel flow, but against it.

Injectors are clean by using an ultrasonic cleaner.
It is a simple process that any automotive injector service centre could perform & it's not that expensive so do it well & do it once.

I think the aussie cricket team could do with putting in an ultrasonic cleaner

I did hear that some engine makers pump oxygen in the manifold and then heat it up. Can't remember the full details though.

Apart from 2 injectors blocked I had another strange event, vapourised fuel coming out of the gas pipe when the engine was running, any ideas why????

The gas port should have a non return/check valve/solenoid valve in line with it.
Otherwise you may vent hot stuff !

What is the make & model of your engine ?
