The fuel filter is located on top of the fuel pump sending unit

To change the fuel filter on a 2003 Dodge Ram diesel, you'll need to locate the fuel pump sending unit assembly, which is found inside the fuel tank. The fuel filter is located on top of this assembly.

There are conflicting reports on whether the fuel filter is inside the fuel tank or not. Some sources suggest that it is an in-line filter, while others claim that it is definitely inside the fuel tank and there is no external filter. However, according to a Dodge dealership parts manager, there is no inline filter, and the fuel filter comes with the pump as part of the sending unit assembly.

To access the fuel filter, you will need to purchase the sending unit assembly. Once you have the assembly, you can simply unscrew the filter housing to replace the filter. This process should take around one hour and only requires some sockets.

The fuel pump is inside the fuel tank

The fuel pump is located inside the fuel tank of your 2003 Dodge Ram diesel. This is true of models manufactured from 2005 onwards, and for 2003 and 2004 models, a retrofit kit was available to install the pump inside the tank.

To access the fuel pump, you will need to remove the bed of the truck to expose the fuel tank. Once you have located the fuel tank, you will need to disconnect the electrical wires and fuel lines before removing the old pump. Be sure to have a container ready to catch any spilled fuel.

When installing the new fuel pump, be sure to clean the area around the top of the fuel tank to prevent any dirt or debris from falling into the tank. You will also need to connect the new pump to the fuel lines and electrical wiring, ensuring everything is securely connected before turning on the ignition.

It is important to note that working with fuel and electricity can be dangerous, so ensure you take the necessary precautions and have the appropriate tools and knowledge before attempting this repair.
