Injector Seals?

Just noticed while giving my '83 Cab.Gti ( DX coded engine ) its post Winter look over that there was slight movement in my injectors.The car seams to run ok after its Winter hybernation but just querying if this is a sign of my injector seals need replacing and if so, which ones do I need.

they will wobble about slightly, but if you're worried the seals are dirt cheap and easy to repalce. they're fat dohnut stylee ones and usually green. GSF should have no trouble supplying you with a set. its a case of a good hard yank after drowning in penetrating oil, then sdwp the new seals on after a liberal smothering of grease then shove back in till they are felt to 'click' in place
