P38A injector rail leak

hello all again after this week of striping out air inlet manifold in my spare time I have gound my dreaded smell of petrol a injector is ****ing out petrol and not just a little so wondered if some kind person could guide me on wether this is a seal jobbie or best to replace complete rail , I have it stripped ready to do either job well rail not out yet but I wont to do a job that will last and not a bodge and alsp is it best to replace all inlet seals gaskets while ive got it stripped or not as im probably going to get inlet properly cleaned as I want it to shine and look good ontop of me engine
any help gratefull you nice lot of people

There are seals on the face to the manifold on a classic, guess a p38 should be too

I have found hat the o ring seal s are knackered and ordered some more today so hopefully arrive tuesdy and job tam to polish up air inlet and clean everthing possible
