Thanks for the instructions, Greg. I just replaced both hoses on my '84300Dt. I just cut the old ones to get them out of the way, figured there had to be a trick and found your post. I already had the filter housing out for other reasons, so just removed that bracket under the IP, moved the A/C compressor, and I kid you not it took all of 30 seconds each to get the new hoses in place.

Thanks!
