Attention: TDR Forum Junkies 
After breaking my 5th potmetal AFC line, I decided I was no longer going to pay Cummins $25 (or Dodge $55) for a little piece of hose with a loop on one end, and a 1/4" air hose ferrule on the other. So, for under $5, i have come up with the following solution- I'll try to explain now in text, but will post pics as soon as I can to clarify my gibberish.
You will need-
~6" 1/8" OD air line
2x 1/8" ferrules and end caps to complement them
1x adaptor- 1/8NPT on one end, 5/16" for ferrule end cap on the other.
1x 5/16" coarse thread double union for 1/8" OD hose
1. Remove the old/broken AFC hose
2. Remove the elbow coming out of the intake that the old AFC hose screwed into.
3. Take an adaptor (1/8" NPT on one end, whatever size for 1/8" OD air line on the other [also found in many oil pressure guage install kits]) and screw the 1/8NPT end into the intake. The adaptor may or may not have an elbow; choice is yours.
4. Take a 1/8" ferrule and end cap doo hickie and attach a piece of 1/8" OD air line to the adaptor from step 3.
5. On the AFC housing, screw in a double union of the same size for 1/8" OD air line. The union is, I believe, a 5/16, and the AFC housing is 8mm. Doing the math, based on 1"=25. 4mm, it comes out to a 0. 0625mm difference. If you feel uncomfortable with this, a double wrap of teflon tape should take up any slack.
6. Attach the other end of the line, with ferrule and end cap doo-hickie, to the union you just screwed into the AFC housing.
Now you have a functioning AFC again, have your full power back, and even if you go to NAPA, are $20 ahead of the game. If you are going for a show-n-shine, and want it to look stock, you will have to get the dealer (Cummins or Dodge) item. If you are just after performance, and saving money any way you can, without cutting corners, this is your ticket. I have tried this, and response/ power/ performance is just as fast as with the stock or replacement hose.
