Name the Gasket

I've just noticed a couple of leaks coming from these areas So I suspect the seals are just needing changed but i'm not sure what seals they are.

First one is this.



The second one i'm not sure exactly where the leak is coming from but I've circled the area that's always wet.

Well picture number two are the fuel injection pipes. Or to be more precise the injection nozzles. There is an "O" ring under each nozzle that may be worth changing.

Picture one I can't quite make out but Landy Zone members are like buses. Wait a couple of minutes and another one will be along soon
