Here's a general outline of the process. Remember, this is a simplified overview, and you should consult a repair manual specific to your 1994 Dodge Ram 1500 for detailed instructions, torque specifications, and safety precautions. Improperly performing this repair could lead to serious injury or damage to your vehicle.
Tools you'll likely need:
* Vehicle lift or jack stands: Absolutely essential for safety. Never work under a vehicle supported only by a jack.
* Fuel pump removal tool: This specialized tool makes removing the pump much easier. Improvising can damage the fuel pump.
* Socket set and wrenches: Various sizes will be needed for removing fuel lines, tank straps, etc.
* Safety glasses and gloves: Protect yourself from fuel and sharp edges.
* Fuel line disconnect tool: These tools help prevent damage to the fuel lines.
* Wrenches for fuel tank straps
* Shop rags or absorbent material: To clean up any spilled fuel.
* Drain pan: For collecting fuel.
* New fuel pump: Get the correct one for your specific engine.
* New fuel filter (recommended): While you're in there, it's a good idea to replace this.
* New fuel pump gasket/O-ring: Essential for a leak-free seal.
* Torque wrench: Ensure proper tightening of bolts to prevent leaks.
* Fuel pressure gauge (optional but recommended): To test fuel pressure after installation.
Steps (general outline – refer to your repair manual for specifics):
1. Safety First: Disconnect the negative battery cable. This prevents sparks that could ignite fuel vapors.
2. Drain the Fuel Tank: Carefully siphon or drain as much fuel as possible from the tank. This reduces the amount of fuel you'll need to handle.
3. Raise the Vehicle: Securely lift the truck using a lift or jack stands.

5. Disconnect the Electrical Connector: Unplug the fuel pump's electrical connector.
6. Lower the Fuel Tank: Locate and disconnect the tank straps. Carefully lower the fuel tank. You may need to support it with a jack or straps as you lower it.
7. Access the Fuel Pump: Locate the fuel pump access on the top of the fuel tank. This usually involves removing a cover or retainer.
8. Remove the Fuel Pump: Use the fuel pump removal tool to carefully remove the pump assembly.
9. Install the New Fuel Pump: Install the new fuel pump, ensuring the gasket/O-ring is properly seated.
10. Reassemble: Carefully reassemble everything, making sure all connections are secure.
11. Reconnect the Fuel Lines and Electrical Connector: Carefully reconnect all fuel lines and the electrical connector.
12. Raise the Fuel Tank: Carefully raise the fuel tank back into place and secure it with the tank straps.
13. Reconnect the Battery: Reconnect the negative battery cable.
14. Test the System: Check for leaks and ensure the fuel pump is functioning correctly. You should also use a fuel pressure gauge to verify fuel system pressure.
Again, this is a simplified outline. A repair manual specific to your 1994 Dodge Ram 1500 is crucial for a safe and successful repair. If you're not comfortable with this level of car repair, take your vehicle to a qualified mechanic. This is a job that can easily go wrong and lead to injury or more expensive repairs if not done correctly.
