DD13 with a bad fuel pump. What to look for and how to repair Part 1

DD13 with low power, check engine lights, multiple fault codes for fuel pressure. This is what we found once we connected to the truck, we performed a Fuel System Integrity Check (FSIC). This is a pass or rail test, a failed result could be injectors or fuel pump but what we found helped us towards the fuel pump. Metal debris is usually an indicator of a bad fuel pump.
