DeatschWerks 4-00-VB40AX1 Single Pump 40 Amp Voltage Booster

$399.00

$399.00

The DeatschWerks 4-00-VB40AX1 Single Pump 40 Amp Voltage Booster is designed to maximize the output of your existing fuel system by providing a stable, increased voltage supply to the fuel pump. This increase in voltage allows a single pump to flow significantly more volume, supporting higher horsepower levels without the immediate need for a multi-pump setup or larger fuel lines.

By maintaining consistent voltage even under heavy load, this booster ensures stable fuel rail pressure and prevents lean conditions caused by electrical system voltage drop. It is a critical upgrade for forced induction or high-performance naturally aspirated engines where fuel demand exceeds the standard 12V-13.5V output.

  • Manufacturer Part Number: 4-00-VB40AX1
  • Current Capacity: 40 Amps
  • Application: Single Fuel Pump
  • Ensures consistent fuel delivery under high-load conditions
  • Compact design for flexible mounting and integration
