Location:
* Fuel Tank: Both the fuel pump and sending unit are located inside the fuel tank, typically accessed from under the truck.
Fuel Filter:
The fuel filter on a 1996 Dodge Ram 5.9L V8 is *not* located in the fuel tank. It's typically found along the frame rail, somewhere between the fuel tank and the engine. It's a cylindrical canister, often with a metal or plastic housing. Check your owner's manual or a repair manual for the exact location; it varies slightly depending on options and specific trim level.
Cleaning the Fuel Sending Unit (Not Recommended):
1. Safety First: Disconnect the negative battery terminal. Fuel is flammable; work in a well-ventilated area, away from any ignition sources.
2. Tank Removal/Drop: This is the most challenging part. You'll likely need to lower or remove the fuel tank. This involves disconnecting fuel lines, electrical connectors, and possibly the tank straps. Support the tank carefully to prevent damage. Consider using jack stands and proper safety procedures.
3. Sending Unit Removal: Once the tank is accessible, locate the sending unit. It's usually held in place by a retaining ring or bolts. Carefully remove it.
4. Cleaning: The sending unit's float and resistance mechanism can be gently cleaned with carburetor cleaner or a suitable electrical contact cleaner. Use compressed air to remove any debris. Do NOT submerge it in any cleaning fluid. The float may have a small vent hole; make sure it isn't clogged.
5. Reassembly: Carefully reassemble the sending unit, making sure the float moves freely.
6. Tank Reinstallation: Reinstall the fuel tank, ensuring all connections are secure. Reconnect the negative battery terminal.
Why Replacement is Usually Better:
* Internal Damage: The problems causing issues with the sending unit or pump (like corrosion or debris) are often internal and not easily cleaned.
* Cost vs. Effort: The cost of a new sending unit or fuel pump is usually less than the time and effort involved in the cleaning process, especially if you lack experience with this type of repair.
* Reliability: A new unit will provide better reliability and performance.
Important Note: If the fuel pump is failing, it's *strongly recommended* to replace it. A failing pump can leave you stranded and could cause further damage to the fuel system. Trying to clean it is highly unlikely to succeed.
Before attempting this repair, consult a repair manual specific to your 1996 Dodge Ram 5.9L V8. This will provide detailed instructions, diagrams, and torque specifications. If you're uncomfortable performing this repair yourself, consider taking your truck to a qualified mechanic. Working with fuel systems requires caution and the right tools.
