Have a 2018 2500 and squirter's have quit working. Hood jets do not appear to be plugged. When activated fluid dribbles out. Pump sounds like it is running but no flow. Will any model 18 pump work for replacement or does it have to be 2500 diesel? Dealer quoted $108+ for replacement pump. I'm thinking junkyard bottle and pump assembly which would make for an easier replacement. Anyone's thoughts on this?
