I have that exact skimmer, however i must have bought mine (or received a model) that did not come with the surface pipe. I think i bought mine in 2012. My unit has the same pump, but has a plastic guard over the location where the surface pipe attaches. I can see when i take it apart to clean, that the pump has threads on its head (intake area).
If http://www.coralvue.com/reef-octopus-classic-100-venturi-intake-basket-499 will work with my skimmer, i will order that part through your website.
