Truck is a diesel. Fuel pump blew up and died in the middle of the street. Now I'm being told the fuel system needs completely re done and will cost me 10g. I also found a lawsuit for this issue as well.
Fuel filter housing contains a primer pump. Needed for a diesel. Seals within that pump failed allowing air into the system. Vehicle is 8 years old and only has 67k miles on it. This caused the motor to quit while in motion. In yellowstone park.
