The Ti Automotive BKS1001-4 is the complete brushless E5LM fuel pump kit: the high-pressure, high-flow E5LM brushless screw pump plus its PWM-input controller. It is rated at 550+ LPH at 13.5V / 40 psi, supports 1,000+ horsepower, and draws less current with less heat and noise than a comparable brushed pump. Suitable for naturally aspirated and boosted builds.
Features
- High-pressure, high-flow E5LM brushless positive-displacement screw pump
- 550+ LPH at 13.5V / 40 psi; supports 1,000+ horsepower
- PWM input command controller with sealed, weather-resistant electronics
- Reduced system current draw, heat and noise
- Simple power and ground connections
- Optional speed control: a PWM input slows the pump, reducing flow by 350-370 LPH from maximum
Controller input signal
- 100 Hz square wave switching between battery voltage and ground
- 95-100% duty cycle in: 100% duty cycle to the pump
- 10-95% duty cycle in: linear output across the range
- Very low duty cycle in: pump off
- Signal wire grounded: 45% duty cycle
Included
- E5LM brushless fuel pump
- PWM controller
- Inlet filter
- Wiring harness, instruction sheet and wiring diagram
Notes
- Direct-fit replacement, designed for in-tank installation only
- Ti Automotive sells the pump and controller together as a kit
