Yes, and i am describing a method how you can test your theory that when it cools down the "gunk" will not recondense.

If the injector does not survive, you can try injector to heated copper pipe to teflon tube to cooled copper pipe.

Have it first shoot in to a bucket of water or exhaust gas bag untill the o2 in the system is consumed/ejected then you could try it in the air.

If successfull you have a precisely metered vapor injection system with a bit of delay. After this you can try adjusting the hot zone length and cold zone length.
