Before you start: Disconnect the negative battery terminal to prevent accidental sparks.
Here's a general outline, but you'll need a repair manual specific to your 1999 Dodge Ram year, model, and engine to get precise instructions and diagrams. A Haynes or Chilton manual is a good investment.
1. Safety First: Work in a well-ventilated area. Gasoline fumes are flammable and dangerous. Wear safety glasses and gloves.
2. Locate the fuel tank: This is usually under the bed of the truck.
3. Prepare for tank access: You may need to:
* Raise the truck: Use jack stands for safety. Never work under a vehicle supported only by a jack.
* Remove the bed: On some models, this might be necessary, requiring removal of tail lights, bed bolts, etc. This is a significant undertaking.
* Lower the fuel tank (preferred method): This is usually possible without completely removing the tank. You'll need to disconnect fuel lines, electrical connectors, and possibly a tank strap or support.
4. Disconnect the fuel lines and electrical connector: Be prepared for some fuel spillage – have rags ready. Carefully relieve fuel pressure in the fuel system before disconnecting the fuel lines. Consult your repair manual for the procedure. This often involves cycling the ignition switch several times.
5. Remove the fuel pump access cover: Once you have access to the top of the fuel tank, you'll likely find a round access cover. This cover needs to be removed to access the fuel pump. This may involve removing bolts or clips.
6. Access and replace the fuel pump: Once the cover is off, you should see the fuel pump assembly. The procedure for removal and installation varies depending on the model. The repair manual will give you specific instructions.
7. Reassemble everything: Make sure all connections are secure, the fuel lines are correctly reconnected, and the access cover is properly sealed.
8. Lower the truck (if raised): Lower the truck slowly and carefully.
9. Recheck fuel connections: Inspect for leaks.
10. Reconnect the battery terminal: Start the engine and check for any issues.
This is a complex repair job. If you're not comfortable working on cars or trucks, take your vehicle to a qualified mechanic. Improperly handling fuel lines or working with gasoline can be dangerous. A professional will have the right tools and experience to do the job safely and correctly.
