Pump Information
We've put together a fuel pump data sheet to make easy comparison for you, see the chart below. Detailed below is the importance of data points.
Flow - This will dictate the amount of fluid that can be moved. LPH = liters per hour
Max Pressure - This is important when you consider your base fuel pressure plus the maximum pressure under full load/boost. Fuel pump flow decreases as pressure increases, so it’s essential to choose a pump that can maintain sufficient flow at your maximum pressure (base fuel pressure + boost pressure). Pumps operating outside their optimal range will experience significant flow drop-off, potentially causing fuel starvation. While higher fuel pressure can increase injector flow, this is only effective if the fuel pump can sustain the pressure without sacrificing flow.
HP Rating - Rating is based on Flow and Fuel Requirement Calculation. This is a conservative number and actual results may vary.
Control Required - A simple relay would be like in our Fuel Pump Relay Kits controlled by a trigger from your car's ECU. A Proprietary Controller is included with most of these brushless pump kits and control strategies will be specific to that controller's construction. The TI Automotive EL5M is now being offered separate of the controller and can be operated by and Aftermarket PDM Unit with the correct parameters provided by TI.
Controller Included - This tells you if you need to consider additional components to operate your fuel pump.
Max Amps -
High-performance fuel pumps demand careful consideration of their electrical needs. Proper wiring, relays, fuses, and a capable charging system are essential to ensure consistent fuel delivery, protect components, and maintain overall system reliability. Skimping on electrical upgrades can lead to voltage issues, pump underperformance, and even catastrophic electrical failures. Always plan your wiring and electrical setup based on the pump(s) max amperage rating and the total demands of your fuel system.
Wire Count - This is important when considering multiple fuel pumps. Please see information regarding our Bulkhead Connection and plan accordingly.
Install Kit Required - Yes means you will need additional components to be compatible with our hanger. This could mean Fuel Sock Filter, Fuel Pump Connector, Fuel Tubes, or Clamps. Choose the appropriate install kit for your fuel pump.
Components Included - What all is included when you add pumps to this kit
Check Valve - If you are staging pumps and your secondary pump does not have a check valve it is essential to install an aftermarket check, otherwise you will bleed pressure though the pump that is off.
Fuel Pump Relay Kit
The PHR Wiring Harness for Dual or Triple Fuel Pumps makes installation seamless. No sourcing hardware, spending time analyzing relay pinouts or any mistakes. Simply run your power to the battery, connect your ground, connect your trigger and run the outputs to your fuel pumps.
This harness uses 30amp fuses and relays for each individual pump for circuit protection as well as a 60amp fuse to protect the entire system. Trigger with simple one wire hookup.
