The fuel filter on a Dodge Ram is located inside the gas tank. The only way to change the filter is to drop the tank and remove the entire pump assembly.
Most Dodge Ram owners are quite shocked to learn that the fuel filter is located inside the gas tank. It can be quite costly to replace since the entire unit must be replaced and the gas tank removed in order to do so.
To replace a fuel filter on a Dodge Ram with a gasoline engine, remove the fuel pump relay from the power distribution center.
Start the engine, and run it until it stalls. Start the engine again, and run it until it stalls. Repeat this step until the engine no longer starts and then turn off the ignition.
Next, disconnect the negative battery cable, and disconnect the fuel tank. Remove the filter from the rubber grommet, and remove the fuel line after the hose clamp has been cut.
Replace the old filter with the new one by pushing the new filter into the rubber grommet, and attach the filter with a new clamp. Put the fuel tank back into place, and reconnect the negative battery cable.
Start the engine, and check for leaks.
