Thanks Clipperjay, once i'v got new ones will the others just pull without any tools?
Problem is some of the larger rubber rings have moulded it self to the collets (brass inserts)
I found the best way to remove them was push from inside out the manifold most people try really too hard and end up ripping off the end of the injector and falling into the manifold. For the sake of a gasket I took mine completely off and gentley pushed them out with a solid flat tool or wood piece. There are two rubber seals you need one thick donut one and a really thin one that sits on the end of the injector(see picture) these are the ones that are usually perished. I think donut ones are the hardest to pull out with the injector in and are the ones that is usually stuck. If yours wobbles it should pop out quite easily.....I say LOL!

Top tip lube up the rubber ring before inserting it goes past the collets by about 3-4mm much easier.
If not pused in properly it will piss fuel or let air in!
