Tools and Materials Needed
- Socket set
- Wrench set
- Fuel line disconnect tool
- New fuel pump
- Fuel filter
- New fuel lines
- Wire connectors

Step 1: Safety First
Before starting the installation, ensure you are working in a well-ventilated area. Wear safety glasses and gloves to protect yourself from fuel and debris.
Step 2: Prepare the Vehicle
Begin by disconnecting the negative battery terminal to prevent any electrical shorts. Next, relieve the fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Step 3: Access the Fuel Tank
To access the fuel tank, remove the rear seats and locate the fuel pump access panel. Unscrew the panel and disconnect any wiring harnesses attached to the fuel pump.
Step 4: Remove the Old Fuel Pump
Using the fuel line disconnect tool, carefully detach the fuel lines from the old fuel pump. Be prepared for some residual fuel to spill out. Remove the retaining ring and take out the old pump from the tank.
Step 5: Install the New Fuel Pump
Place the new fuel pump into the tank and secure it with the retaining ring. Reconnect the fuel lines, ensuring they are snug and leak-free. Reattach the wiring harness to the new pump.
Step 6: Replace the Fuel Filter
Locate the fuel filter on the vehicle. Disconnect the fuel lines and remove the old filter. Install the new fuel filter in the same orientation as the old one and reconnect the fuel lines.
Step 7: Upgrade Fuel Lines
Replace the old fuel lines with the new ones provided in the upgrade kit. Ensure all connections are secure and that there are no kinks in the lines.
Step 8: Reassemble the Access Panel
Once everything is installed, reattach the fuel pump access panel and secure it with screws. Replace the rear seats to restore the interior.
Step 9: Reconnect the Battery
Reconnect the negative battery terminal. This will restore power to the vehicle and allow you to test the new fuel system.
Step 10: Test the System
Turn the ignition to the “On” position without starting the engine. This will prime the fuel system. Check for any leaks around the fuel pump and lines. If everything looks good, start the engine and let it idle.
Conclusion
Upgrading your Z1 Motorsports 300ZX Twin Turbo fuel system is a rewarding project that can significantly enhance your vehicle’s performance. By following these steps, you can ensure a successful installation and enjoy the benefits of your new fuel system.
