Lift Pump Flow Rates:

95gph is recommended for stock to 600HP applications. This is the kit for most people.
150gph is recommended for 600HP to 700HP applications.
200gph is recommended for 700HP+ applications only.
*You do not want to run a pump with a higher gallon per hour rating than your engines horsepower or the life of the fuel pump will be greatly reduced. Pump noise is greatly enhanced with the larger flowing pumps.
