RPM Air Gap water hose question

Use a brass threaded pipe nipple from the hardware store. You cut the pipe 3/4" longer than the threads. It's smooth for more surface to clamp too.

I reinstalled the original short pipe fitting from the M1. but try as I may there is no way to get a hose to bend without it kinking. I have ordered a Mopar Performance silicone hose that I am understanding will work without collapsing too bad, saw it install and keeping finger crossed it works.
Wonder what next problem will be!
