I just had the vacuum pump go south on my 03 Dually with NV5600. The only thing this pump does is operate the Jake brake. I checked prices from 2 dealers, one was $695. 00 and the other $750. 00. This was just for the pump itself, nothing else. I ordered one from Cummins and had it installed in 25 minutes myself and it cost me $88. 10. It even comes with a new pulley already attached. I think this is far over and above price gouging!!
Do it yourself and save $800. 00. Thanks for nothing D/C!!!!)
