I own a 2006 40 ft Alpine. On last trip a Turbocharger hose got a hole in it causing a loss of power. I have it at a Cummins dealer and this hose is not a Cummins part. The hose is about 4 inches in diameter and has a 90degree bend in it. It has 2 sets of numbers on it. 90-400-16 and A0518. Any ideas where we could get this part? Thanks, Doug

Do a search on this forum for part number and source--this is a common problem with newer coaches. Make sure you get the higher temp orange color hose and not the original blue color, low temp hose...
