Doug,

They have an O-ring on them........Try soaking them with WD-40 then

gently try to break them loose by pushing them out from inside the manifold.

I have had good luck using this method but be careful they will break.....

I think the consensus of opinion is that the primary diffusers in the center

iron housing are more useful to help idle......most do not seem to be using

the ones for the secondary injectors.........
