Well I think you'd be hard pressed to knock a hole on one...they are pretty thick aluminum...put a hole in it and you have much bigger problems else where on the truck too...knock it off the tank?... possible but highly doubtful...the only thing that is vulnerable is the hose and maybe the barb...keep in mind you can clock the sump to where the barb and hose is behind the sump and also the thing only protrudes about 2-1/2 inches below the tank at most...on the duramax tank I have the sump placed about where the front spring perch is so where you can place it on a 6.5 may affect yours differently...
