Here's why this is important:
* Electric Fuel Pump: The Cummins turbo diesel in your 1990 Ram uses an electric fuel pump that's submerged in the fuel tank. This pump is responsible for drawing fuel from the tank and sending it to the engine.
* Access: To access the fuel pump, you'll need to drop the fuel tank. This is a more involved job compared to accessing an engine-mounted fuel pump.
Note: It's essential to refer to a service manual specifically for your 1990 Dodge Ram with the Cummins engine for detailed instructions and safety precautions related to working on the fuel system.
