Does this help at all?

Does this help? Let me know if you need more I can send tonight

Looks like you've got help on the FD cable routing. I can't help on that one because both U.P. builds in my house are Di2.

I did just build my wife's New U.P. up with SRAM eTap Hydraulics. You will break the hydraulic hoses at the brifter end. The end barbs on the SRAMs are factory pressed into the inside of the hoses so these will be tossed with the cut off hose sections. You can pull the compression collets (olives?) for reuse. Typically SRAM will include a couple of the hose barbs and olives reinforcement nipples with your brake kit. If you don't have these I believe they are offered as them as Thingamajig kit with barbs, olives and a torx wrench for the barbs.

I found the SRAM hydraulic set up pretty easy to work with. I did have to find longer flat mount brake bolts for the front brake. Routing the front brake hose was also a bit challenging, but I used some of my aerobar cable routing tricks to get it done.

We love our U.P.'s!

Me too. I was a little surprised they would send out bolts that don't work. They sent me 32 mm, after I contacted them they said I need 37 mm. They spec titanium bolts, so I don't understand the point of sending out $15 bolts that can't be used for anything.

Yes, pay someone who does this on a regular basis to do it, you'll be happy you did ;-)

It sounds like you've got the Force1 or Rival1 HRD group. You'll need the Sram bleed kit, dot grease, and some dot fluid. Their online video is pretty helpful, but if this is your first time, you may end up having to do it more than once.
