There are two types, as far as I know, one with the quick-release connectors and the "cheaper version (E model) fitted without them. Other than that they should be exactly the same.

You can, get the right connectors to upgrade the pump housing to accept the quick release connectors. Or you could do it the other way round and remove the quick release connectors off the pipes and connect it directly to the tank!

I think we have some of the right quick release connectors if you need them, so let me know.
