On a trip with my 2018 Duramax last August we got a tank full of rusty water fuel at a Velero station near Proctor AR called PJ Travel Center. Less than one hundred miles started my problems dropped fuel filter, full of rust and water. Got truck running sounded great completed trip and kept changing filter with less and less debris finally clean. Truck only pulls camper and never goes in the winter so low 20000 miles pristine truck. Fast forward to this week started up engine light on so scoped 3 injectors need replaced, opened it up and rust in the high pressure lines, rail, injection pump, tank pump, lines, remove and flush tank. $9000. Needles to say the GM filter system is a complete joke DO NOT GO ANOTHER MILE WITHOUT AN UPGRADED DOUBLE FILTER INSTALL.
