Here's a general outline of what's involved. Again, this is dangerous if you don't know what you're doing. Consider professional help:
1. Safety First: Disconnect the negative battery terminal. Fuel is highly flammable. Work in a well-ventilated area, away from any sparks or open flames. Consider using safety glasses and gloves.
2. Fuel Tank Removal: This involves:
* Raising the vehicle: Securely lift the truck using jack stands. Never work under a vehicle supported only by a jack.
* Disconnecting the fuel lines: Carefully release the fuel lines using appropriate wrenches. You'll need to relieve pressure in the fuel system (often by starting the engine and letting it run until it stalls, or by using a fuel pressure gauge to safely relieve pressure). Have rags ready to absorb any spilled fuel.
* Disconnecting the fuel tank electrical connector: This is likely a single connector. You may need to use a small pry tool or a connector release tool to separate it.
* Lowering the fuel tank straps: Carefully lower the fuel tank. It will be heavy and potentially contain some fuel, so proceed slowly and cautiously.
3. Accessing the Fuel Pump Connector: Once the fuel tank is lowered, you should be able to access the fuel pump. The electrical connector will be attached to the top or side of the pump. Disconnect it carefully.
4. Reassembly: Reverse the process to reinstall the fuel tank. Be sure to reconnect all fuel lines and electrical connectors securely.
5. Check for Leaks: After reassembly, inspect for any fuel leaks.
Tools You'll Likely Need:
* Jack and jack stands
* Wrenches (various sizes)
* Fuel line disconnect tools
* Socket set
* Pry tool or connector release tool
* Safety glasses
* Gloves
* Rags
* Possibly a fuel pressure gauge
Recommendation: This is a complex and potentially dangerous repair. Unless you have extensive experience working on automotive fuel systems, it's strongly recommended to take your vehicle to a qualified mechanic. Improper handling of fuel systems can lead to serious injury or fire.
