Ti/Walbro 525 LPH Brushless In-Tank Fuel Injection Pump Kit - E85 Compatible
Walbro BKS1001 525 LPH Brushless Fuel Pump - E85 Compatible
TI Automotive (Walbro) manufactures a complete line of fuel pumps, accessories, pump kits, and fuel modules for the high-performance aftermarket. Approximately two-thirds of the vehicles produced around the world feature TI Automotive’s products and technology. TI Automotive’s award-winning fuel delivery system technology is featured on some of the world’s highest performing production vehicles and supercars.
Walbro's E85 compatible 525 LPH Brushless High Pressure In-Tank Fuel Pump is designed for ultra high performance vehicles. It delivers impeccable performance and high volumes of fuel flow.
The Walbro 525 LPH Brushless In-Tank Fuel Pump (PN:BKS1001) flows 525 lph (138.7 gph) at 3 Bar and is capable of supporting 1000+ HP under standard operating conditions. Please see the graphs below for more information.
The BKS1001 is the next generation of our popular BKS1000 high pressure direct-fit fuel pump kit. Now with PWM (pulse-width modulation) control, you’ll enjoy a true three-step controller with functions for 100% duty cycle, 50% duty cycle by grounding the command wire, and full PWM command by wiring the input to a 100Hz battery level PWM signal. More customization at the controller level means more power for your ride.

Variable PWM control will need to be customised to your vehicle. Unchanged, the controller will default to the vehicle's stock program.
This controller can be run without being connected to the vehicle ECU using the following options:
- Option 1 - Ground the orange wire to run controller at 45% constant duty cycle.
- Option 2 - Leave the orange wire disconnected to run controller at constant 100% duty cycle
A 20A fuse with a 40A relay is recommended.
