MSD's programmable Fuel Pump Booster increases voltage to the factory fuel pump in proportion to manifold boost pressure to maintain proper fuel delivery after adding a turbo or supercharger. The voltage increase is adjustable via MSD's Windows-based PC software, and the booster wires to the factory fuel pump relay or a secondary booster pump.
Specifications:
- Maximum Output Voltage: 22 volts
- Voltage Increase Range: Additional 1.5-22 volts
- Boost Range: Up to 30 psi
- Programming: Fully programmable via PC (Windows software), adjustable pressure vs. voltage graph
- Monitoring: Real-time voltage and amperage gauge display
- Mounting: Any position, fully potted for vibration resistance
- Compatibility: Stock electric fuel pumps or secondary booster pumps
- Warranty: Manufacturer's Limited 1-Year Warranty
- Part Number: 2351
Note: Cannot be used on fuel systems without a return line (pulse-modulated pumps).
Compliance: This part is legal for sale and use on Racing Use Only Vehicles — competition vehicles that are not registered and never operated on the street. It is against the law to install this part on an Emissions Controlled Vehicle (1966-and-newer California-certified or 1968-and-newer federally certified vehicles).
