1. Introduction
The Briidea Electric Fuel Pump Controller, Model HFPC-01, is designed to manage the operation of an electric fuel pump in automotive applications. This controller facilitates the upgrade from a mechanical fuel pump to an electric system by providing intelligent control based on engine operation. Its primary function is to ensure the fuel pump is active only when the engine is running, enhancing safety and efficiency.

2. Product Features
- Tach Signal Monitoring: The controller monitors the engine's tachometer signal. The pump operates only when a tach signal is detected, indicating the engine is running. An indicator light on the unit illuminates when the pump is operational.
- Enhanced Safety: In the event of an engine stall, the controller automatically cuts off power to the fuel pump after a brief delay, preventing continuous fuel delivery and reducing potential hazards.
- Intelligent Start-up: Upon ignition, the fuel pump is energized for approximately three seconds to prime the fuel system. After this initial period, the pump will only remain energized if a tach signal is present, ensuring fuel is supplied only when the engine is actively starting or running.
- Universal Fit: Designed for broad compatibility with various vehicle types.
3. Setup and Installation
Proper installation is critical for the safe and correct operation of the Briidea Electric Fuel Pump Controller. Ensure the vehicle's battery is disconnected before beginning installation.
3.1 Wiring Connections
Refer to the wiring diagram below for detailed connection instructions:

Image 3.1: Electrical connection diagram for the fuel pump controller.
- Red Wire: Connect to a switched 12V power supply in the vehicle. This should be active when the ignition is on.
- Black Wire: Connect to vehicle ground (GND).
- Green Wire: Connect to the tachometer signal lead. This signal indicates engine RPM.
- Purple Wires (x2): These wires are for the external electric fuel pump. One purple wire connects to an external 12V power supply (often the same switched 12V as the red wire, but dedicated for the pump), and the other connects to the positive (+) terminal of the external fuel pump. An optional diode may be required for certain pump types; consult your fuel pump's instructions. The line on the diode should face the + side of the pump.
3.2 Physical Installation
Mount the controller in a secure location away from excessive heat, moisture, and vibration. Ensure all connections are tight and properly insulated to prevent short circuits.

4. Operating Instructions
Once installed, the Briidea Electric Fuel Pump Controller operates automatically based on the vehicle's ignition and engine status.
- Ignition On: When the vehicle's ignition is turned on, the controller will energize the fuel pump for approximately three seconds. This primes the fuel system for engine start-up.
- Engine Starting/Running: After the initial three-second prime, the fuel pump will only remain active if the controller detects a tachometer signal, indicating the engine is cranking or running. The 'Pump On' indicator light on the controller will illuminate.
- Engine Stalled/Off: If the engine stalls or is turned off, the tachometer signal will cease. The controller will then cut off power to the fuel pump, typically within a few seconds, to prevent continuous fuel flow when the engine is not operating.

5. Maintenance
The Briidea Electric Fuel Pump Controller is designed for maintenance-free operation. Periodically inspect all wiring connections for corrosion or looseness. Ensure the unit is free from excessive dirt or moisture. No user-serviceable parts are inside the controller.
6. Troubleshooting
If the fuel pump controller is not functioning as expected, consider the following troubleshooting steps:
- Pump Not Priming (No 3-second activation):
- Verify the red wire has a consistent 12V switched power supply when the ignition is on.
- Check the black wire connection for a secure ground.
- Pump Does Not Stay On After Engine Starts:
- Ensure the green wire is correctly connected to a reliable tachometer signal source.
- Confirm the tach signal is present and strong enough for the controller to detect.
- Pump Remains On Continuously (Does Not Shut Off with Engine):
- Re-check the green wire connection to the tach signal. An incorrect or missing tach signal can cause the controller to default to continuous operation.
- Verify the tach signal is clean and not experiencing interference.
- Pump Randomly Shuts Off During Operation:
- Inspect all wiring connections, especially the tach signal and power wires, for intermittent contact or loose terminals.
- Ensure the vehicle's electrical system is providing stable voltage.
If issues persist after troubleshooting, consult a qualified automotive technician.
