🔧 Install Tips
- Safety First: Disconnect the battery and manage residual fuel pressure carefully before opening the tank assembly.
- Pro Install Recommended: We highly recommend professional installation for EFi components due to the precise diagnostics required.
- Upgrade the Reg/Rec: If you’ve had electrical issues in the past, consider our Japanese MOSFET Regulator upgrade to prevent future voltage spikes that fry electronics. View Reg/Rec Mod Kit here.
