heard from a gm tech that if you don't have a stand alone water separator on your Duramax your warranty will be void? and if so, what one would you use? and where would you put it?

someone pullin your leg??????

good luck

The water separator is in the filter. Bad information from that guy.

wouldnt hurt to ha ve a extra seperator but thier already is one he doesnt know what hes talking aboutmaybe shouldntget him to work on youer truck
