Tools and Materials Needed
Before starting the installation, gather the following tools and materials:
- DeatschWerks DW300C Fuel Pump
- Fuel Pump Installation Kit
- Socket set
- Wrench set
- Phillips and flathead screwdrivers
- Fuel line disconnect tool
- Safety glasses
- Rags for spills
Step-by-Step Installation Process
Step 1: Prepare the Vehicle
Start by ensuring your vehicle is parked on a flat surface. Turn off the engine and disconnect the negative battery terminal to prevent any electrical issues during the installation.
Step 2: Access the Fuel Pump
To access the fuel pump, you will need to remove the rear seat cushion. Locate the clips at the front of the seat and pull them up to release the cushion.
Next, locate the fuel pump access cover, which is typically found under the seat. Remove the screws securing the cover and lift it off to expose the fuel pump assembly.
Step 3: Disconnect the Fuel Lines
Using a fuel line disconnect tool, carefully detach the fuel lines from the pump. Be prepared for some fuel spillage, so have rags ready to catch any excess fuel.
Step 4: Remove the Old Fuel Pump
Unbolt the fuel pump assembly from its mounting bracket. Carefully lift the assembly out of the tank, ensuring not to damage any surrounding components.
Step 5: Install the DeatschWerks DW300C Pump
Remove the old pump from the assembly and replace it with the DeatschWerks DW300C pump. Ensure that it is securely fitted and that all seals are in place to prevent leaks.
Step 6: Reassemble the Fuel Pump Assembly
Once the new pump is installed, carefully place the assembly back into the fuel tank. Secure it with the bolts you removed earlier.
Step 7: Reconnect the Fuel Lines
Reconnect the fuel lines to the new pump, ensuring they are securely fastened. Double-check for any signs of damage or wear on the lines.
Step 8: Replace the Access Cover and Seat
Once everything is connected, replace the fuel pump access cover and secure it with the screws you removed earlier. Then, reinstall the rear seat cushion by aligning it with the clips and pushing down until it clicks into place.
Step 9: Reconnect the Battery and Test
Reconnect the negative battery terminal. Start the engine and check for any leaks around the fuel pump area. It’s important to let the engine idle for a few minutes to ensure everything is functioning correctly.
