I guess a soft face dead blow hammer or a peice of wood to protect the housing is what i should have said. The snap ring can be hard to remove so make sure you have a good pair or snap ring pliers.

I didnt find a way to get the snapring loose, so i did the wood and hammer method. worked really well to my surprise (i hate using hammers like this though). IC piping is now installed, and im making good progress.
