You need to buy some #3 90* elbows for the lines going into the nozzles. That should fix the problem you are having. The hose as it is isnt bending sharp enough to not rub the hood.

Thanks for the mention VetteNoob...
It was one of the things that slowed down my install of the TNT system. I had to order some 90's from Pure Choice ( http://www.performanceplumbing.com/ )
TNT also does a poor job of providing an adequate IAC port on their plate. That sucker needed some major reaming to meet spec. But what do you expect for the $650 entry price? None of these N2O providers really have a terrific product at the introductory price point.

The IAC (Idle Air Control) stepper motor controls the idle air which is introduced through small ports in each intake runner.
There's about a 5/8" hole in the front of the intake manifold which mates up to semi-triangular shaped area on the back of the throttle body that lets IAC air and a bit of IAC bypass air make it to the small ports.
The TNT plate has a woefully undersized IAC opening. It's a big deal if you've got a properly sealed up throttle body (i.e. no worn bushings, throttle plates, and good gaskets to prevent inadvertent air leakage).
Here's a pic of an enlarged TNT IAC port. I matched up this size to the hole on the front of the intake manifold. Not pictured, I also drilled another hole directly on top of this one and filed until I had merged the pair into a semi-triangular shape to match the rear of the throttle body. It helped my idle immensely.
