Can anyone identify these connectors and fuel lines from on my pump assembly?

On second thought I'll guess. #5 looks like part of the fuel pressure regulator and #6 is the in tank return.

Thanks Guzzler. #5 is a small nipple on top of the fpr. I believe it controls the diaphram via vacuum. I was just making sure since I can't find much info about it.
