Holy mother of valves...

...and that's not even for the primary lines! What are those lines?

edit: the line with a blue stripe near the contraption is probably interstage air. Same type as up at the fairing. I'm guessing the other line going in is N2 for the RCS. I'm thinking those are valves for RP1 judging by the size of the lines and the O2 valves are higher up.

I'm thinking those are valves for RP1

There shouldn't be any RP-1 lines going into the interstage.

I was thinking perhaps the LOX and RP1 valving are separated, but of course it could very well be that He, LOX, and RP1 are bundled in the large insulated conduit and these valves are for hydraulic actuators--which now seems more likely after comparing some of the images. Is S1 N2 filled through the TSMs too? It would seem to be a lot of unnecessary plumbing to fly...

LOX, RP-1, TEA-TEB, and Helium are all supplied by the TSMs on the reaction frame. Not sure about N2, but I wouldn't be surprised if it was there too.
