Freightliner Cascadia 2013 DD13/ Fuel pump issues

It's been a learning curve for mechanics with the DD motors as to priming the fuel system. Davco has a machine, some use pump sprayers, some just hand pump. I decided to just use Speedco. The stand alone ones. Not Loves. They have it down pat. Plus I figure they have enough money I can sue them if they F it up.
Hard and worrysome owning a truck. A simple PM shouldn't make you lose sleep. Feel your pain. Been there. Like I said, become as knowledgeable as you can about your equipment. Its your best defence and piece of mind. It took a couple of years of getting solidly screwed up the behind for me to learn this. Take it for what you will. Good luck.
