Needs pics of your Coolant Re-Route Route
His is a PWR. I had a PWR and my reroute's upper radiator hose also rested on the intercooler/TB pipe. Annoyed me since the same thing happened with the old FMII kit and OEM upper radiator hose. Was going to have a 90* elbow welded onto the radiator so that it would clear, but never got around to it before parting the car.
My oh my, somebody knows how to use the flower button! 
I'll post these now since my internet is currently working (fingers crossed). I know it's an over the radiator setup, but it's the stock hose with an inch or so cut off each end, so you can get an idea for how much room it'll give you.

I have no clearance at all on my 1.8 with the BEGI up pipe and a Godspeed rad. The rad hose is squished against the IC pipe hard enough I used that coil stuff inside to keep the hose open. I shortened the rad inlet and the IC up pipe just to get to that stage with the big rad. I need to move the rad slightly forward some how and get these things some space. Hate the rubbing.
I decided to use a piece of regular hose with bends that allow the rear portion to sit on the shelf. The thermostat itself (not in view in this photo) is actually right behind the shock tower brace. I wrapped old hose over any place where it might actually make contact with anything just to ensure it doesn't rub.

First it was like this...

Then it went like this...

Quickly followed by this...


(The new hose I will be using once I get a tube to connect the rear hose with this one)

And then all the sudden it was like this...


Now I just need to build some shroud and I'm good.

Here is the first routing I had on my VVT car. But realized the hose was above the radiator so now it is shoved down below the intake. It's kind of in a U-shape though. The hose is too long and I need to cut it. I still need to get the air out of the system fully though because it is overheating for a minute on warmup before cooling back down.
It's difficult to tell because of the angle of the photo, but it looks like that extra bend in your reroute hose is sitting in a high spot, perhaps even higher than the radiator cap? Air could collect there and make it difficult to bleed. Do like the rest of us and cut it down and bring it closer to the intake mani to eliminate that bent section. You want the rad cap to be the highest point in the system.

So you guys that used a pipe to connect a short hose at the radiator to the longer hose coming from the back; two questions:
1. What did you use for the pipe?
2. Did you weld a bead on the pipe ends to keep the hoses on?

I used a copper pipe with screw on fittings soldered on and slipped the rubber hose on the screw on fittings with a bunch of thread sealant on them. I'm returning the coolant from my stock oil cooler to another fitting off the copper pipe as well.
Thanks to a local forum member, the pipe used on my reroute pictured above was a 14" piece of aluminum pipe, polished, beaded on the ends, and had a 1/4" NPT bung welded on with a 1/4" NPT to 5/16" barb fitting for the throttle body coolant return line (you can see this near the front of it on the underside).
This is an old build picture:

That's nice. A bit more elaborate than my needs though. I'm thinking of maybe trying to find a 32mm inline coolant sensor adaptor and using that if I can't find something suitable at Lowe's /Home Depot, or NAPA.
I've since moved to this setup:

With my heater core return and coolant sensor in a piece spliced into the lower hose.
