TI Automotive (Walbro) BKS1001 Brushless Intank Fuel Pump Kit

Brushless technology with variable speed control pumps up to 550lph (at 40psi).

• rated for use with petrol and E85
• for between 650 and 1000hp applications
• suitable for both naturally aspirated and forced induction applications
• reduced system current draw
• reduced noise compared with traditional pumps
• maximum system pressure 7.72bar (112psi)
• 39mm diameter
• includes variable speed controller (pump and controller not available separately)

 

Operating Modes - Speed Controller Wire	Pump Duty Cycle
Wired to Ground	45%
1 to 4% Duty Cycle @ 100Hz	0% (pump off)
5 to 9% Duty Cycle @ 100Hz	45%
10 to 95% Duty Cycle @ 100Hz	45 to 100%
96 to 100% Duty Cycle @ 100Hz	100% (full speed)
Disconnected	100% (full speed)

Two speed control can easily be setup by putting the speed control wire to ground to flow 70% less fuel (from full speed).  Connect the speed control wire to a PWM output to have full variable speed control (from 45% to 100% duty cycle).
