Ford actually uses plastic fuel pumps on their diesel engined vehicles in the US, that means trucks like this:
Have all-plastic fuel pumps in them.
Over 100 PSI goes through an all-plastic pump, which would get hot and expands and contracts as it cools down, right next to a hot differential.
Sure, I can understand they want to shed weight, but making it from a lighter material won't make a difference on 5500 lb. truck.
EDIT: Not to sure what this has to do with the new Mustang, but whatever.
