So, I had a lot of people tell me when I first brought this issue up, "Just plum it back into the intake?" and I didn't quite understand it until I looked at your picture. So, I pulled out my Mopar M1 intake and realized that manifold had an extra threaded section for a nipple to be threaded into to reroute the heater hose in there. I found a post on FABO that explained all the holes and ports on an LD4B and apparently it doesn't have that threaded hole to reroute the heater hose. Instead there is a threaded boss to mount an AC compressor.
