Yes and no. To a point, you can have more flow than you need but you DO NOT want excessive pressure. Many customers choose to purchase a 150gph pump for the stock/mild upgrades because the price difference between the 95gph and 150gph is so little. This is fine as the pressure will still be at the recommended pressure for your vehicle.
Having a pump that is larger than 150gph on a stock or slightly modified truck can cause issues. Vehicles that actually need larger units are mainly purpose-built competition vehicles and can handle higher pressures. Along with other competition specific parts, these pumps are going to be much louder. Performance of the motor will produce added pressure which will create more amp draw and lessen the electric motor life. Please select the FASS Diesel Fuel System for your application.
