This is a general overview and might not cover every specific detail for your exact van. Always consult a repair manual specific to your year, model, and engine for precise instructions and torque specifications. A Haynes or Chilton manual is a good investment.
Before You Begin:
* Safety First: Disconnect the negative battery terminal. Allow the fuel system pressure to depressurize (this usually takes a while, but you can speed it up with methods described in your repair manual). Work in a well-ventilated area, away from any ignition sources. Wear safety glasses and gloves.
* Gather Tools: You'll need a variety of tools, including sockets, wrenches, screwdrivers (possibly including Torx bits), pliers, a fuel pump removal tool (often a special tool is recommended, but a strong clamp can sometimes work), and possibly a fuel line disconnect tool. You'll also need jack stands and safety stands, as you'll be working under the vehicle. Consider having a fuel pump strainer and gasket ready for replacement as well.
* Obtain a Replacement Fuel Pump: Ensure you purchase the correct fuel pump for your specific vehicle's engine and fuel system.
General Steps (This is NOT a comprehensive guide):
1. Lower the Fuel Tank: This is the most challenging part. You'll likely need to access the fuel tank straps from underneath the van. You might need to remove the spare tire and possibly other components to gain access. Support the tank with jack stands while lowering it. The tank is heavy and requires careful handling.
2. Disconnect Fuel Lines: Once the tank is lowered enough, carefully disconnect the fuel lines. This usually involves releasing clamps or using specialized tools. Be prepared for some fuel spillage – have absorbent material ready. Mark or photograph the lines to ensure correct reassembly.
3. Disconnect Electrical Connector: Unplug the electrical connector to the fuel pump.
4. Remove the Fuel Pump Assembly: This step often involves removing a retaining ring or cover. A fuel pump removal tool can be helpful here, but you may be able to maneuver the assembly out using other tools.
5. Replace the Fuel Pump: Carefully remove the old fuel pump from the assembly. Install the new fuel pump, ensuring it's seated correctly.
6. Reassemble: Reinstall the fuel pump assembly, making sure everything is secure. Reconnect the electrical connector and fuel lines, ensuring no leaks.
7. Raise the Fuel Tank: Carefully raise the fuel tank back into place and secure it with the straps.
8. Reconnect the Battery: Reconnect the negative battery terminal.
9. Prime the Fuel System: You might need to prime the fuel system (consult your repair manual for instructions). This is usually done by turning the ignition key several times to cycle the pump.
10. Check for Leaks: Carefully inspect all connections for leaks.
Important Considerations:
* Fuel Pressure: The fuel system needs to be properly depressurized before working on it. Failure to do so can lead to a fire or injury. Your repair manual will have specific instructions for your vehicle.
* Fuel Spillage: Expect some fuel spillage. Have absorbent material ready and take proper precautions.
* Tank Straps: These can be very difficult to remove and reinstall, and often require specialized tools or a lot of patience and skill.
