you need two a two part PVC Primer and PVC Glue. The primer will clean the sections, but more importantly color is purple a bit so that you know you've glued it, which is good if it's your first if it's your first time plumbing. Prime the sections which will be glued into each other.
Then put glue on the inside of the bulkhead and the outside of the pvc, making sure it's well coated. Then slide the PVC in, and turn it at least 90 degrees in both directions and hold it there for a few seconds. The PVC has a tendency to want to pop back out, which is no good, since we are wanting stuff to NOT leak.
I'll see if i can't find anything on google to show you....
