I'm changing the water pump on my IE, everything has gone very smoothly so far with much better access to it than I first thought. I've got the new pump (which is the right one

) it comes with the gasket to fit pump to block but there's no gasket for pump to lower water rail.
I was going to use some instant gasket silicone sealant, is this the norm? or should it come with a gasket of some type?
