Blame engine vibration and chintzy bonding on the core-to-tank ends of 6.4L Ford Power Stroke engine’s radiator tanks (which are plastic) for causing cracks that lead to coolant leaks. This concern plagues nearly all of these powerplants. The problem ultimately can promote severe engine damage from overheating.
Normal operating high pressure to drive the injectors is about 5,500 psi, with pressure increasing depending on load. The high pressure pump delivers fuel to the fuel rails through two high pressure lines (one per bank).

Where is the fuel pressure sensor on a 6.4 Powerstroke?
Where is the fuel pressure regulator on a 6.4 Powerstroke?
The fuel pressure regulator is located inside the engine mounted fuel filter housing in the standpipe.
How do you bleed a fuel system on a 6.4 Powerstroke?
What happens when a diesel pump fails?
Symptoms of a failing fuel pump may include: Jerks or sputters at high speeds. Power loss on acceleration. Power loss while driving up a slope.
What does a failed bubble test mean?
If bubbles indicating a leak are present under full vacuum or the rise of vacuum, the package failed the bubble emission test. If fluid resides inside of the packaging system after the test, the packaging also failed the test.
How does the 6.4 Powerstroke fuel system work?
The 6.4L Power Stroke Diesel engine uses a high pressure fuel injection pump to deliver fuel to each piezo electric fuel injector via a high pressure common fuel rail, one rail per bank. The 6.4L Power Stroke Diesel uses a four (4) valve per cylinder head design to optimize airflow and efficiency.
Where is the fuel pressure regulator located on a 6.7 Powerstroke?
In a 6.7L Powerstroke engine, the fuel rail pressure sensor location is on the fuel rail between the middle and the end of the rail. It connects to the engine’s ECU. If you have any trouble locating the pressure sensor, find your fuel railand follow it until you find the sensor bolted to the rail.
What does the fuel rail pressure sensor do?
It is a part of vehicle’s fuel system and designed to monitor the fuel pressure that is present at the fuel rail. The sensor sends this signal to the computer, which then uses it to make adjustments to the vehicle’s fuel and timing. When the sensor has an issue it can cause problems with the performance of the vehicle.
High fuel pressure will make an engine run rich, while low fuel pressure will make an engine run lean or not at all. Fuel pressure readings that are higher than manufacturers specifications are generally caused by a problem in the return line fuel components.
What causes a P0087 code?
Diagnostic Trouble Code (DTC) P0087 stands for “Fuel Rail/System Pressure Too Low.” It may get logged by the PCM when the pressure inside the fuel rail or the fuel system dives below the minimum levels needed to supply the engine with enough fuel to run properly.
